Brain waves


  1. Delta wave – (0.1 – 3 Hz)
  2. Theta wave – (4 – 7 Hz)
  3. Alpha wave – (8 – 15 Hz)
  4. Mu wave – (7.5 – 12.5 Hz)
  5. SMR wave – (12.5 – 15.5 Hz) 
  6. Beta wave – (16 – 31 Hz)
  7. Gamma wave – (32 – 100 Hz)
Beta wave, or beta rhythm, is the term used to designate the frequency range of human brain activity between 12.5 and 30 Hz (12.5 to 30 transitions or cycles per second). Beta waves are split into three sections: Low Beta Waves (12.5–16 Hz, "Beta 1 power"); Beta Waves (16.5–20 Hz, "Beta 2 power"); and High Beta Waves (20.5–28 Hz, "Beta 3 power").[1] Beta states are the states associated with normal waking consciousness.


Low amplitude beta waves with multiple and varying frequencies are often associated with active, busy, or anxious thinking and active concentration.
Over the motor cortex beta waves are associated with the muscle contractions that happen in isotonic movements and are suppressed prior to and during movement changes. Bursts of beta activity are associated with a strengthening of sensory feedback in static motor control and reduced when there is movement change. Beta activity is increased when movement has to be resisted or voluntarily suppressed. The artificial induction of increased beta waves over the motor cortex by a form of electrical stimulation called Transcranial alternating-current stimulation consistent with its link to isotonic contraction produces a slowing of motor movements.

Hair colours

Hair is mainly keratin, the same protein found in skin and fingernails. The natural color of hair depends on the ratio and quantities of two other proteins, eumelanin and phaeomelanin. Eumelanin is responsible for brown to black hair shades while phaeomelanin is responsible for golden blond, ginger, and red colors. The absence of either type of melanin produces white/gray hair. Bleach is used to lighten hair. The bleach reacts with the melanin in hair, removing the color in an irreversible chemical reaction. The bleach oxidizes the melanin molecule. The melanin is still present, but the oxidized molecule is colorless. However, bleached hair tends to have a pale yellow tint. The yellow color is the natural color of keratin, the structural protein in hair. Also, bleach reacts more readily with the dark eumelanin pigment than with the phaeomelanin, so some gold or red residual color may remain after lightening. Hydrogen peroxide is one of the most common lightening agents. The peroxide is used in an alkaline solution, which opens the hair shaft to allow the peroxide to react with the melanin.

History of Japan




Heisei (平成?) is the current era in Japan. The Heisei era started on 8 January 1989, the first day after the death of the reigning Emperor, Hirohito. His son, Akihito, succeeded to the throne. In accordance with Japanese customs, Hirohito was posthumously renamed"Emperor Shōwa" on 31 January. On 7 January 1989, at 07:55 JST, the grand steward of Japan's Imperial Household Agency, Shōichi Fujimori, announced Emperor Shōwa's death, and revealed details about his cancer for the first time. Shortly after the death of the Emperor, Keizō Obuchi, then Chief Cabinet Secretary and later Prime Minister of Japan, announced the end of the Shōwa era, and heralded the new era name "Heisei" for the new incoming Emperor, and explained the meaning of the name. According to Obuchi, the name "Heisei" was taken from two Chinese history and philosophy books, namely Records of the Grand Historian (史記 Shiji) and the Classic of History (書経 Shujing). In the Shiji, the sentence "内平外成" (nèi píng wài chéng;Kanbun: 内平かに外成る Uchi tairaka ni soto naru) appears in a section honoring the wise rule of the legendary Chinese Emperor Shun. In the Shujing, the sentence "地平天成" (dì píng tiān chéng; Kanbun: 地平かに天成る Chi tairaka ni ten naru) appears. By combining both meanings, Heisei is intended to mean "peace everywhere". The Heisei era went into effect immediately after the announcement of the new emperor on 8 January 1989.

 The Shōwa period (昭和時代 Shōwa jidai?), or Shōwa era, is the period of Japanese history corresponding to the reign of the Shōwa Emperor, Hirohito, from December 25, 1926, through January 7, 1989.[1] The Shōwa period was longer than the reign of any previous Japanese emperor. During the pre-1945 period, Japan moved into politicaltotalitarianism, ultranationalism and fascism culminating in Japan's invasion of China in 1937. This was part of an overall global period of social upheavals and conflicts such as the Great Depression and the Second World War. Defeat in the Second World War brought about radical change to Japan. For the first and only time in its history, Japan was occupied by foreign powers; this occupation lasted seven years. Allied occupation brought forth sweeping democratic reforms. It led to the end of the emperor's status as a living god and the transformation of Japan into a democracy with a constitutional monarch. In 1952, with the Treaty of San Francisco, Japan became a sovereign nation once more. The post-war Shōwa period also led to the Japanese economic miracle. In these ways, the pre-1945 and post-war periods regard completely different states: the pre-1945 Shōwa period (1926–1945) concerns the Empire of Japan, while post-1945 Shōwa period (1945–1989) was a part of the State of Japan.

Legure

Legure ili slitine su krute otopine metala u metalu, bez određenog stehiometrijskog omjera atoma koji čine leguru. Legure točno određenog stehiometrijskog sastava nazivaju se intermetalni spojevi. Miješanjem čiste kovine s nekom drugom kovinom, ili nemetalom (npr. ugljik), dobiva se slitina ili legura boljih svojstava od ishodnog materijala. Legiranje povećava čvrstoću, tvrdoću i otpornost prema koroziji.

Bakar i kositar su svaki za sebe slabi i suviše savitljivi, ali kad se pomiješaju čine čvrstu leguru - broncu. Mjed je tvrda legura bakra i cinka otporna na koroziju, a aluminijske legure su lagane i čvrste i koriste se za gradnju aviona.

Nordijsko zlato je legura koja se rabi za izradu medalja ili kovanica (kovanice EU od 10, 20 i 50 centi načinjene su od nordijskog zlata). Usprkos nazivu, zlato nije sastojak ove legure, nego:

The Stone of the Philosophers by Edward Kelly

Though I have already twice suffered chains and imprisonment in Bohemia, an indignity which has been offered to me in no other part of the world, yet my mind, remaining unbound, has all this time exercised itself in the study of that philosophy which is despised only by the wicked and foolish, but is praised and admired by the wise. Nay, the saying that none but fools and lawyers hate and despise Alchemy has passed into a proverb. Furthermore, as during the preceding three years I have used great labour, expense, and care in order to discover for your Majesty that which might afford you much profit and pleasure, so during my imprisonment - a calamity which has befallen me through the action of your Majesty - I am utterly incapable of remaining idle. Hence I have written a treatise, by means of which your imperial mind may be guided into all the truth of the more ancient philosophy, whence, as from a lofty eminence, it may contemplate and distinguish the fertile tracts from the barren and stony wilderness. But if my teaching displease you, know that you are still altogether wandering astray from the true scope and aim of this matter, and are utterly wasting your money, time, labour, and hope. A familiar acquaintance with the different branches of knowledge has taught me this one thing, that nothing is more ancient, excellent, or more desirable than truth, and whoever neglects it must pass his whole life in the shade. Nevertheless, it always was, and always will be, the way of mankind to release Barabbas and to crucify Christ. This I have - for my good, no doubt - experienced in my own case. I venture to hope, however, that my life and character will so become known to posterity that I may be counted among those who have suffered much for the sake of truth. The full certainty of the present treatise time is powerless to abrogate. If your Majesty will deign to peruse it at your leisure, you will easily perceive that my mind is profoundly versed in this study.

(1) All genuine and judicious philosophers have traced back things to their first principles, that is to say, those comprehended in the threefold division of Nature. The generation of animals they have attributed to a mingling of the male and female in sexual union; that of vegetables to their own proper seed; while as the principle of minerals they have assigned earth and viscous water.

(2) All specific and individual things which fall under a certain class, obey the general laws and are referable to the first principles of the class to which they belong.

(3) Thus, every animal is the product of sexual union; every plant, of its proper seed; every mineral, of the mixture of its generic earth and water.

(4) Hence, an unchangeable law of Nature regulates the generation of everything within the limits of its own particular genus.

(5) It follows that, with reference to their origin, animals are generically distinct from vegetables and minerals; the same difference exists respectively between vegetables and minerals and the two other natural kingdoms.

(6) The common and universal matter of these three principles is called Chaos.

(7) Chaos contains within itself the four elements of all that is, viz., fire, air, water, and earth, by the mixture and motion of which the forms of all earthly things are impressed upon their subjects.

(8) These elements have four qualities: heat, coldness, humidity, dryness. The first inheres in fire, the second in water, the third in air, the fourth in earth.

(9) By means of these qualities, the elements act upon each other, and motion takes place.

(10) Elements either act upon each other, or are acted on, and are called either active or passive.

(11) Active elements are those which, in a compound, impress upon the passive a certain specific character, according to the strength and extent of their motion. These are water and fire.

(12) The passive elements - earth and air - are those which by their inactive qualities readily receive the impressions of the aforesaid active elements.

(13) The four elements are distinguished, not only by their activity and passivity, but also by the priority and posteriority of their motions.

(14) Priority and posteriority are here predicated either with references to the position of the whole sphere, or the importance of the result or aim of the motion.

(15) In space, heavy objects tend downwards, and light objects upwards; those which are neither light nor heavy hold an intermediate position.

(16) In this way, even among the passive elements, earth holds a higher place than air, because it delights more in rest; for the less motion, the more passivity.

(17) The excellence of result has reference to perfection and imperfection, the mature being more perfect than the immature. Now, maturity is altogether due to the heat of fire. Hence fire holds the highest place among active elements.

(18) Among the passive elements, the first place belongs to that which is most passive, i.e., which is most quickly and easily influenced. In a compound, earth is first passively affected, then air.

(19) Similarly, in every compound, the perfecting element acts last; for perfection is a transition from immaturity to maturity.

(20) Maturity being caused by heat, cold is the cause of immaturity.

(21) It is clear, then, that the elements, or remote first principles of animals, vegetables, and minerals, in Chaos, are susceptible of active movements in fire and water, and of passive movements in earth and air. Water acts on earth, and transmutes it into its own nature; fire heats air, and also changes it into its own likeness.

(22) The active elements may be called male, while the passive elements represent the female principle.

(23) Any compound belonging to any of these three kingdoms - animal, vegetable, mineral - is female in so far as it is earth and air, and male in so far as it is fire and water.

(24) Only that which has consistency is sensuously perceptible. Elementary fire and air, being naturally subtle, cannot be seen.

(25) Only two elements, water and earth, are visible, and earth is called the hiding-place of fire, water the abode of air.

(26) In these two elements we have the broad law of limitation which divides the male from the female.

(27) The first matter of vegetables is the water and earth hidden in its seed, these being more water than earth.

(28) The first matter of animals is the mixture of the male and female sperm, which embodies more moisture than dryness.

(29) The first matter of minerals is a kind of viscous water, mingled with pure and impure earth.

(30) Impure earth is combustible sulphur, which hinders all fusion, and superficially matures the water joined to it, as we see in the minor minerals, marcasite, magnesia, antimony, etc.

(31) Pure earth is that which so unites the smallest parts of its aforesaid water that they cannot be separated by the fiercest fire, so that either both remain fixed or are volatilized.

(32) Of this viscous water and fusible earth, or sulphur, is composed that which is called quicksilver, the first matter of the metals.

(33) Metals are nothing but Mercury digested by different degrees of heat.

(34) Different modifications of heat cause, in the metallic compound, either maturity or immaturity.

(35) The mature is that which has exactly attained all the activities and properties of fire. Such is gold.

(36) The immature is that which is dominated by the element of water, and is never acted on by fire. Such are lead, tin, copper, iron, and silver.

(37) Only one metal, viz., gold, is absolutely perfect and mature. Hence it is called the perfect male body.

(38) The rest are immature and, therefore, imperfect.

(39) The limit of immaturity is the beginning of maturity; for the end of the first is the beginning of the last.

(40) Silver is less bounded bu aqueous immaturity than the rest of the metals, though it may indeed be regarded as to a certain extent impure, still its water is already covered with the congealing vesture of its earth, and it thus tends to perfection.

(41) This condition is the reason why silver is everywhere called by the Sages the perfect female body.

(42) All other metals differ only in the degree of their imperfection, according as they are more or less bounded by the said immaturity; nevertheless, all have a certain tendency towards perfection, though they lack the aforesaid congealing vesture of their earth.

(43) This congealing force is the effect of earthy coldness, balancing its own proper humidity, and causing fixation in the fluid matter.

(44) The lesser metals are fusible in a fierce fire, and therefore lack this perfect congealing force. If they become solid when cool, this is due to the arrangement of their aforesaid earthy particles.

(45) According to the different ways in which this viscous water and pure earth are joined together, so as to produce quicksilver by coagulation, with the mediation of natural heat, we have different metals, some of which are called perfect, like gold and silver, while the rest are regarded as imperfect.

(46) Whoever would imitate Nature in any particular operation must first be sure that he has the same matter, and, secondly, that this substance is acted on in a way similar to that of Nature. For Nature rejoices in natural method, and like purifies like.

(47) Hence they are mistaken who strive to elicit the medicine for the tinging of metals from animals or vegetables. The tincture and the metal tinged must belong to the same root or genus; and as it is the imperfect metals upon which the Philosopher's Stone is to be projected, it follows that the powder of the Stone must be essentially Mercury. The Stone is the metallic matter which changes the forms of imperfect metals into gold, as we may learn from the first chapter of "The Code of Truth": "The Philosophical Stone is the metallic matter converting the substances and forms of imperfect metals"; and all Sages agree that it can have this effect only by being like them.

(48) That Mercury is the first matter of metals, I will attempt to prove by the saying of some Sages.
In the Turba Philosophorum, chapter i., we find the following words: "In the estimation of all Sages, Mercury is the first principle of all metals."
And a little further on: "As flesh is generated from coagulated blood, so gold is generated out of coagulated Mercury."
Again, towards the end of the chapter: "All pure and impure metallic bodies are Mercury, because they are generated from the same."
Arnold writes thus to the King of Aragon: "Know that the matter and sperm of all metals are Mercury, digested and thickened in the womb of the earth; they are digested by sulphureous heat, and according to the quality and quantity of the sulphur different metals are generated. Their matter is essentially the same, though there may be some accidental differences, such as a greater or less degree of digestion, etc. All things are made of that into which they may be resolved, e.g., ice or snow, which may be resolved into water; and so all metals may be resolved into quicksilver; hence they are made out of quicksilver."
The same view is set forth by Bernard of Trevisa, in his book on the "Transmutation of Metals": "Similarly, quicksilver is the substance of all metals; it is as a water by reason of the homogeneity which it possesses with vegetables and animals, and it receives the virtues of those things which adhere to it in decoction." A little further on the same Trevisan affirms that "Gold is nothing but quicksilver congealed by its sulphur."
And, in another place, he writes as follows: "The solvent differs from the soluble only in proportion and degree of digestion, but not in matter, since Nature has formed the one out of the other without any addition, even as by a process equally simple and wonderful she evolves gold out of quicksilver."
Again: "The Sages have it that gold is nothing but quicksilver perfectly digested in the bowels of the earth, and they have signified that this is brought about by sulphur, which coagulates the Mercury, and digests it by its own heat. Hence the Sages have said that gold is nothing but mature quicksilver."
Such also is the concensus of other authorities. "The Sounding of the Trumpet" gives forth no uncertain note: "Extract quicksilver from the bodies, and you have above the ground quicksilver and sulphur of the same substance of which gold and silver are made in the earth."
The "Way of Ways" leads to the same conclusion: "Reverend Father, incline they venerable ears, and understand that quicksilver is the sperm of all metals, perfect and imperfect, digested in the bowels of the earth by the heat of sulphur, the variety of metals being due to the diversity of their sulphur."
We find in the same tract a similar canon: "All metals in the earth are generated in Mercury, and thus Mercury is the first matter of metals."
To these words Avicenna signifies his assent in chapter iii.: "As ice, which by heat is dissolved into water, is clearly generated out of water, so all metals may be resolved into Mercury, whence it is clear that they are generated out of it."
This reasoning is confirmed by "The Sounding of the Trumpet": "Every passive body is reduced to its first matter by operations contrary to its nature; the first matter is quicksilver, being itself the oil of all liquid and ductile things."
So also the third chapter of the "Correction of Fools": "The nature of all fusible things is that of Mercury coagulated out of a vapour, or the heat of red or white incumbustible sulphur."
In chapter i. of the "Art of Alchemy" we read: "All Sages agree that the metals are generated from the vapour of sulphur and quicksilver."
Again, a passage in the Turba Philosophorum runs thus: "It is certain that every subject derives from that into which it can be resolved. All metals may be resolved into quicksilver, hence they were once quicksilver."
If it were worth while, I might adduce hundreds of other
passages from the writings of the Sages, but as they would serve no good purpose, I will let these suffice.
Those persons make a great mistake who suppose that the thick water of Antimony, or that viscous substance which is extracted from sublimed Mercury, or from Mercury and Jupiter dissolved together in a damp spot, can in any case be the first substance of metals.
Antimony can never assume metallic qualities, because its water and moisture are not tempered with dry, subtle, earth, and want, moreover, that unctuosity which is characteristic of malleable metals. But, as Chambar well says in the "Code of Truth": "It is only through jealousy that Sages have called the Stone Antimony."
In the same way, those who destroy the natural composition of Mercury, in order to resolve it into a thick or limpid water, which they call the first matter of metals, fight against Nature in the dark, like blinded gladiators.
As soon as Mercury loses its specific form, it becomes something else, which cannot thenceforth mingle with metals in their smallest parts, and is made void for the work of the Philosophers. Whoever is taken up with such childish experiments, should listen to the Sage of Trevisa in his "Transmutation of Metals":
"Who can find truth that destroys the humid nature of Mercury? Some foolish persons change its specific metallic arrangement, corrupt its natural humidity by dissolution, and disproportionate quicksilver from its original mineral quality, which wanted nothing but purification and simple digestion. By means of salts, vitriol, and alum, they destroy the seed which Nature has been at pains to develop. For seed in human and sensitive things is formed by Nature and not by art, but by art it is united and mixed. Seed needs no addition, and brooks no diminution. If it is to produce a new thing of the same genus, it must remain the very same thing that was formed by Nature. All teaching that changes Mercury is false and vain, for this is the original sperm of metals, and its moisture must not be dried up, for otherwise it will not dissolve. Too much fire will cause a morbid heat, like that of a fever, and change the passive into active elements, thus the balance of forces is destroyed, and the whole work marred. Yet these fools extract from the lesser minerals corrosive waters, into which they project the different species of metals, and thus corrode them.
"The only natural solution is that by which out of the solvent and the soluble, or male and female, there results a new species. No water can naturally dissolve metals except that which abides with them in substance and form, which also the dissolved metals can again congeal; this is not the case with aqua fortis, seeing that it only destroys the specific arrangement. Only that water can rightly dissolve metals which is inseparable from them in fixation, and such a water is Mercury, but not aqua fortis, or any thing else which those fools are pleased to call Mercurial Water." Thus far Trevisan.
Persons who have fallen into this fatal error may also derive benefit from the teaching of Avicenna on this point: "Quicksilver is cold and humid, and of it, or with it, God had created all metals. It is aerial, and becomes volatile by the action of fire, but when it has withstood the fire a little time, it accomplishes geat marvels, and is itself only a living spirit of unexampled potency. It enters and penetrates all bodies, passes through them, and is their ferment. It is then the White and the Red Elixir and is an everlasting water, the water of life, the Virgin's milk, the spring, and that Alum of which whosoever drinks cannot die, etc. It is the wanton serpent that conceives of its own seed, and brings forth on the same day. With its poison it destroys all things. It is volatile, but the wise make it to abide the fire, and then it transmutes as it has been transmuted, and tinges as it has been tinged, and coagulates as it has been coagulated. Therefore is the generation of quicksilver to be preferred before all minerals; it is found in all ores, and has its sign with all. Quicksilver is that which saves metals from combustion, and renders them fusible. It is the Red Tincture which enters into the most intimate union with metals, because it is of their own nature, mingles with them indissolubly in all their smallest parts, and, being homogeneous, naturally adheres to them. Mercury receives all homogeneous substances, but rejects all that is heterogeneous, because it delights in its own nature, but recoils from whatsoever is strange. How foolish, then, to spoil and destroy that which Nature made the seed of all metallic virtue by elaborate chemical operations!"
The "Rosary" bids us be particularly careful, lest in purifying the quicksilver we dissipate its virtue, and impair its active force. A grain of wheat, or any other seed, will not grow if its generative virtue be destroyed by excessive external heat. Therefore, purify your quicksilver by distillation over a gentle fire.
Says the Sage of Trevisa: "If the quicksilver be robbed of its due metallic proportion, how can other substances of the same metallic genus be generated from it? It is a mistake to suppose that you can work miracles with a clear limpid water extracted from quicksilver. Even if we could get such a water, it would not be of use, either as to form or proportion, nor could it restore or build up a perfect metallic species. For as soon as the quicksilver is changed from its first nature, it is rendered unfit for our operation, since it loses its spermatic and metallic quality. I do, indeed, approve of impure and gross Mercury being sublimed and purified once or twice with simple salt, according to the proper method of the Sages, so long as the fluxibility or radical humour of such Mercury remains unimpaired, that is to say, so long as its specific mercurial nature is not destroyed, and so long as its outward appearance does not become that of a dry powder."
In the "Ladder of the Sages" we are told to beware of vitrification in the solution of bodies, with the odour and taste of imperfect substances, and also of the generative virtue of their form being in any way scorched and destroyed by corrosive waters.
If you have been trying to do any of these things, you may see how grievous your mistake has been. For the water of the Sages adheres to nothing except homogeneous substances. It does not wet your hands if you touch it, but scorches your skin, and frets and corrodes every substance with which it comes in contact, except gold and silver (it would not affect these until they have been dissipated and dissolved by spirits and strong waters), and with these it combines most intimately. But the other mixture is most childish, it is condemned by the concert of the Sages, and by my own experience.
I now propose to shew that quicksilver is the water with which, and in which, the solution of the Sages takes place, by putting before the reader the opinions of many Philosophers living in different countries and ages.
Says Menalates in the Turba: "Whoever joins quicksilver to the body of magnesia, and the woman to the man, extracts the hidden nature by which bodies are coloured. Know that quicksilver is a consuming fire which mortifies bodies by its contact."
Another Sage, in the Turba, says: "Divide the elements by fire, unite them through the mediation of Mercury, which is the greatest arcanum, and so the magistery is complete, the whole difficulty consisting in the solution and conjunction. The solution, or separation, takes places through the mediation of Mercury, which first dissolves the bodies, and these are again united by ferment and Mercury."
Rosinus makes Gold address Mercury as follows: "Dost thou dispute with me, Mercury? I am the Lord, the Stone which abides the fire." Says Mercury: "Thou sayest true; but I have begotten thee, and one part of me quickens many of thee, since thou art grudging in comparison with me. Whoever will join me to my brother or sister shall live and rejoice, and make me sufficient for thee."
In the 5th chapter of the "Book of Three Words," we read: "I tell thee that in Mercury are the works of the planets, and all their imaginations in its pages."
Aristotle says that the first mode of preparation is that the Stone shall become Mercury; he calls Mercury the first body, which acts on gross substances and changes them into its own likeness. "If Mercury did nothing else than render bodies subtle and like itself, it would suffice us."
Senior: "Our Stone, then, is congealed water, that is to say, Mercury congealed in gold and silver, and, when fixed, resistent to the fire."
"The Sounding of the Trumpet": "Mercury contains all that the Sages seek, and destroys all flaky gold. It dissolves, softens, and extracts the soul from the body."
"The Book on the Art of Alchemy": "The Sages were first put upon attempting to clothe inferior bodies in the glory and splendour of the perfect body when they discovered that metals differ only according to the greater or smaller degree of their digestion, and are all generated from Mercury, with which they extracted gold and reduced it to its first nature."
The "Correction of Fools": "Observe that crude Mercury dissolves bodies and reduces them to their first matter or nature. Being made of clear water, it always strives to corrode the crude, and especially that which is nearest to its own nature, viz., gold and silver." The same book observes: "You can make use of crude Mercury as follows - to seal up and open natures, since similar things are helpful one to another." Once more: "Quicksilver is the root in the Art of Alchemy, for the Sages say that all metals are of it, and through it, and in it - it follows that the metals must first be reduced to Mercury, the matter and sperm of all metals."
Again: "The reason why all metals must be reduced to the nature of vapour is because we see that all are generated of quicksilver, though the mediation of which they came into being."
Gratianus: "Purify Laton, i.e., copper(ore), with Mercury, for Laton is of gold and silver, a compound, yellow, imperfect body."
"The Sounding of the Trumpet": "Common Mercury is called a spirit. If you do not resolve the body into Mercury, with Mercury, you cannot obtain its hidden virtue."
"Art of Alchemy," chapter vi.: "The second part of the Stone we call living Mercury, which, being living and crude, is said to dissolve bodies, because it adheres to them in their innermost being. This is the Stone without which Nature does nothing."
"Rosary": "Mercury never dies, except with its brother and sister. When Mercury mortifies the matter of the Sun and Moon, there remains a matter like ashes."
The Sage of Trevisa: "Add nothing above ground for digesting and thickening Mercury into the nature of gold or of metals." Again: "This solution is possible and natural, that is to say, by Art as handmaid to Nature, and is unique and necessary in the work; but it is brought about only by quicksilver, in such proportions as commend themselves to a good workman who knows the inmost properties of Nature."
"Art of Alchemy": "Who can sufficiently extol Mercury, for Mercury alone has power to reduce gold to its first nature?"
From these quotations it is clear what the Sages meant by their water, and what they thought of this wonderful liquid, viz., Mercury, to which they ascribed all power in the Magistery, for nothing can be perfected outside its own genus. Men digest vegetables, not in the blood of animals, but in water which is their first principle, nor are minerals affected by the vegetable liquid. In the words of the "Sounding of the Trumpet": "The whole Magistery consists in dividing the elements from the metals, and purifying them, and in separating the sulphur of Nature from the metals."
Furthermore, as Hermes says, only homogeneous substances cohere, and only they can produce offspring after their own kind, i.e., if you want a medicine which is to generate metals, its origin must be metallic, since "species are tinged by their genus," as the philosopher testifies.
In short, our Magistery consists in the union of the male and female, or active and passive, elements through the mediation of our metallic water and a proper degree of heat. Now, the male and female are two metallic bodies, and this I will again prove by irrefragable quotations from the Sages:
Dantius bids us prepare the bodies and dissolve them.
Rhasis: "Change the bodies into water, and the water into earth: then all is done."
Galienus: "Prepare the bodies, and purify them of the blackness in which is corruption, till the white becomes white and red, then dissolve both, etc."
Calid (chapter i.): "If you do not make the bodies subtle, so that they may be impalpable to touch, you will not gain your end. If they have not been ground, repeat your operation, and see that they are ground and subtilized. If you do this, you will be directed to your desired goal."
Aristotle: "Bodies cannot be changes except by reduction into their first matter."
Calid (chapter v.): "Similarly, the Sages have commanded us to dissolve the bodies so that heat adheres to their inmost parts; then we proceed to coagulation after a second dissolution with a substance which most nearly approaches them."
Menabadus: "Make bodies not bodies, and incorporeal things bodies, for this is the whole process by which the hidden virtue of Nature is extracted."
Ascanius: "The conjunction of the two is like the union of husband and wife, from whose embrace results golden water."
"Anthology of Secrets": "Wed the red man to the white woman, and you have the whole Magistery."
"The Sounding of the Trumpet": "There is another quicksilver and permanent tincture which is extracted from perfect bodies by dissolution, distillation, sublimation, and subtilization."
Hermes: "Join the male to the female in their own proper humidity, because there is no birth without union of male and female."
Plato: "Nature follows a kindred nature, contains it, and teaches it to resist the fire. Wed the man to the woman, and you have the whole Magistery."
Avicenna: "Purify husband and wife separately, in order that they may unite more intimately; for if you do not purify them, they cannot love each other. By conjunction of the two natures you get a clear and lucid nature, which, when it ascends, becomes bright and serviceable."
"Art of Alchemy": "Two bodies provide us with everything in our water."
Trevisanus: "Only that water which is of the same species, and can be thickened by bodies, can dissolve bodies."
Hermes: "Let the stones of mixture be taken in the beginning of the first work, and let them be equally mixed into earth."
"Mirror": "Our Stone must be extracted from the nature of two bodies, before it can become a perfect Elixir."
Democritus: "You should first dissolve the bodies over white hot ashes, and not grind them except only with water."
"Rosary" of Arnold: "Extract the Medicine from the most homogeneous bodies in Nature."
I have thus proved the number of the bodies from which the Elixir is obtained. I will now shew by quotations what these bodies are.
"Exposition of the Letter of King Alexander": "In this art you must wed the Sun and the Moon."
"The Sounding of the Trumpet": "The Sun only heats the earth and imparts to it his virtue through the mediation of the Moon, which, of all stars, most readily receives his light and heat."
"The Correction of Fools": "Sow gold and silver, and they will yield to your labour a thousandfold, through the mediation of that thing which alone has what you seek. The Tincture of gold and silver exhibits the same metallic proportions as the imperfect metals, because they have a common first matter in Mercury."
Again: "Tinge with gold and silver, because gold gives the golden and silver the silver colour and nature. Reject all things that have not naturally or virtually the power of tinging, as in them is no fruit, but only waste of money and gnashing of teeth."
Senior: "I, the Sun, am hot and dry, and thou, the Moon, art cold and moist; when we are wedded together in a closed chamber, I will gently steal away thy soul."
Rosinus to Saratant: "From the living water we obtain earth, a homogeneous dead body, composed of two natures, that of the Sun and that of the Moon."
Again: "When the Sun, my brother, for the love of me (silver) pours his sperm (i.e. his solar fatness) into the chamber (i.e. my Lunar body), namely, when we become one in a strong and complete complexion and union, the child of our wedded love will be born."
Hermes: "Its humidity is of the empire of the Moon, and its fatness of the empire of the Sun, and these two are its coagulum and pure seed."
Astratus says: "Whoever would attain the truth, let him take the humour of the Sun and the Spirit of the Moon."
Turba Philosophorum: "Both bodies in their perfection should be taken for the composition of the Elixir, whether orange or white, for neither becomes liquid without the other."
Again, Gold says: "No one kills me but my sister."
Aristotle: "If I did not see gold and silver, I should certainly say that Alchemy was not true."
The Sage: "The foundation of our Art is gold and its shadow."
"Art of Alchemy": "We have already said that gold and silver must be united."
"Rosary": "There is an addition of orange colour by which the Medicine is perfected from the substance of fixed sulphur, i.e., both medicines are obtained from gold and silver."
The Sage: "Whoever knows how to tinge sulphur and quicksilver has reached the great arcanum. Gold and silver must be in the Tincture, and also the ferment of the spirit."
"Rosary": "The ferment of the Sun is the sperm of the man, the ferment of the Moon, the sperm of the woman. Of both we get a chaste union and a true generation."
"The Sounding of the Trumpet": "You want silver to subtilize your gold, and make it volatile by removing its impurity, since the silver has a greater need of the light of gold. Therefore Hermes, as also Aristotle in his treatise on Plants, says that gold is its father, and silver its mother; nothing else is needed for our Stone. Silver is the field in which the seed of gold is sown." And a little further on: "In my sister, the Moon, grows your wisdom, and not in any other of my servants, saith the Lord Sun. I am like seed sown in good and pure soil, which sprouts and grows and multiplies and yields great gain to the sower. I, the Sun, give to thee, the Moon, my beauty, the light of the Sun, when we are united in our smallest parts." And the Moon says to the Sun: "Thou hast need of me, as the cock has need of the hen, and I need thy operation, who art perfect in morals, the father of lights, a great and mighty lord, hot and dry, and I am the waxing Moon, cold and moist, but I receive thy nature by our union."
Avicenna: "In order to obtain the red and the white Elixir, the two bodies must be united. For though gold is the most fixed and perfect of the metals, yet if it be dissolved into its smallest parts, it becomes spiritual and volatile, like quicksilver, and that because of its heat. This tincture, which is without number, is called the hot male seed. But if silver be dissolved in warm water, it remains fixed as before, and has little or no tincture, yet it readily receives the tincture in a temperament of hot and cold, and is called the cold, dry, female seed. Gold or silver by themselves are not easily fusible, but a mixture of the two melts readily, as is well known to goldsmiths. Hence if our Stone did not contain both gold and silver, it would not be liquid, and would yield no medicine through any magistery, nor tincture, for if it yielded tincture it would still have no tinging power."
And a little further on: "Take heed, then, and operate only on gold, silver, and quicksilver, since all the profit of our Art is derived from these three."
I may add that crude Mercury is the water which the Sages have used for the purpose of solution. I have proved that two bodies must be dissolved, and that they are no other than gold and silver. Now I will describe the conjunction of these two bodies by means of the crude Mercury of the Sages.
"The Light of Lights": "Know that it is gold, silver, and Mercury that whiten and redden within and without. The Dragon does not die, unless he be killed with his brother and sister, and it must be not by one, but by both together."
"The Ladder of the Sages": "Others say that a true body must be added to these two, to strengthen and shorten the operation."
"Treasury of the Sages": "Our Stone has body, soul, and spirit, the imperfect body is the body, the ferment the soul, and the water the spirit."
"The Way of Ways": "The water is called the spirit, because it gives life to the imperfect and mortified body, and imparts to it a better form; the ferment is the soul, because it gives life to the body, and changes it into its own nature."
Again: "The whole Magistery is accomplished with our water, and of it. For it dissolves the bodies, calcines and reduces them to earth, transforms them into ashes, whitens and purifies them, as Morienus says: "Azoth and fire purify Laton, that is to say, wash it and thoroughly remove its obscurity; Laton is the impure body, Azoth is quicksilver."
"The Sounding of the Trumpet": "As without the ferment there is no perfect tincture, as the Sages say, so without leaven there is no good bread. In our Stone the ferment is like the soul, which gives life to the dead body through the mediation of the spirit, or Mercury."
"The Rosary" and Peter of Zalentum say: "If the ferment, which is the medium of conjunction, be placed in the beginning, or in the middle, the work is more quickly perfected."
"The Sounding of the Trumpet": "The Elixir of the Sages is composed of three things, viz., the Lunar, the Solar, and the Mercurial Stone. In the Lunar Stone is white sulphur, in the Solar Stone red sulphur, and the Mercurial Stone embraces both, which is the strength of the whole Magistery."
Eximenus: "The water, with its adjuncts, being placed in the vessel, preserves them from combustion. The substances being ground with water, there follows the ascension of the Ethelia and the imbibition of water is sufficient by itself to complete the work."
Plato: "Take fixed bodies, join them together, wash the body in the bodily substance, and let it be strengthened with the incorporeal body, till you change it into a real body."
Pandulphus: "The fixed water is pure water of life, and no tinging poison is generated without gold and its shadow. Whoever tinges the poison of the Sages with the Sun and its shadow, has attained the highest wisdom."
Again: "Separate the elements with fire, unite them by means of Mercury, and the Magistery is complete."
Exercit, 14: "The spirit guards the body and preserves it from fire, the clarified body keeps the spirit from evaporating over the fire, the body being fixed and the spirit incombustible. Hence the body cannot be burnt, because the body and spirit are one through the soul. The soul prevents them from being separated by the fire. Hence the three together can defy the fire and anything else in the world."
Rhasis("Book of Lights"): "Our Stone is named after the creation of the world, being three and yet one. Nowhere is our Mercury found purer than in gold, silver and common Mercury."
When bodies and spirits are dissolved, they are resolved into the four elements, which become a firm and fixed substance. But when they are not both dissolved, there is a particular mixture which the fire can still separate."
Rosinus: "In our Magistery are a spirit and bodies, whence it is said: It rejoices being sown in the three associated substances."
Calid: "Prepare the strone bodies with the dissolves humidity, till either shall be reduced to its subtle form. If you do not subtilize and grind the bodies till they become impalpable, you will not find what you seek."
Rosinus: "The Stone consists of body, soul, and spirit, or water, as the Philosophers say, and is digested in one vessel. Our whole Magistery is of, and by, our water, which dissolves the bodies, not into water, but by a true philosophical solution into the water whence metals are extracted, and is calcined and reduced to earth. It makes yellow as wax those bodies into whose nature it is transformed; it substantialises, whitens, and purifies the Laton, according to the word of Morienus."
Aristotle: "Take your beloved son, and wed him to his sister, his white sister, in equal marriage, and give them the cup of love, for it is a food which prompts them to union. All pure things must be united to pure things, or they will have sons unlike themselves. Therefore, first of all, even as Avicenna advises, sublime the Mercury, and purify in it impure bodies. Then pound and dissolve. Repeat this operation again and again."
Ascanius: "Stir up war between copper and Mercury till they destroy each other and devour each other. Then the copper coagulates the quicksilver, the quicksilver congeals the copper, and both bodies become a powder by means of diligent imbibition and digestion. Join together the red man and the white woman till they become Ethelia, that is, quicksilver. Whoever changes them into a spirit by means of quicksilver, and then makes them red, can tinge every body."
As to the nature of this copper, Gratianus instructs us in the following words: "Make Laton white, i.e., whiten copper with Mercury, because Laton is an orange imperfect body, composed of gold and silver."
I advise all and sundry to follow my teaching, as to the correctness of which my quotations from the ancients can leave no doubt, which also has received further confirmation from my own experiments. Any deviation from this course leads to deception, except only the work of Saturn, which must be performed by the subtilization of principles. The Sages say that homogeneous things only combine with each other, make each other white and red, and permit of common generation. The important point is that Mercury should act upon our earth. This is the union of male and female, of which the Sages say so much. After the water, or quicksilver, has once appeared, it grows and increases, because the earth becomes white, and this is called the impregnation. Then the ferment is coagulated, i.e., joined to the imperfect prepared body, till they become one in colour and appearance: this is termed the birth of our Stone, which the Sages call the King. Of this substance it is said in the "Art of Alchemy" that if any one scorches this flower, and separates the elements, the generative germ is destroyed.
I conclude with the words of Avicenna: "The true principle of our work is the dissolution of the Stone, because solved bodies have assumed the nature of spirits, i.e., because their quality is drier. For the solution of the body is attended with the coagulation of the spirit. Be patient, therefore, digest, pound, make yellow as wax, and never be weary of repeating these processes till they are quite perfect. For things saturated with water are thereby softened. The more you pound the substance, the more you soften it, and subtilize its gross parts, till they are thoroughly penetrated with the spirit and thus dissolved. For by pounding, roasting, and fire, the tough and viscous parts of bodies are separated."
Finally, I do you to wit, sons of knowledge, that in the work of the Sages there are three solutions.
The first is that of the crude body.
The second is that of the earth of the Sages.
The third is that which takes place during the augmentation of the substance. If you diligently consider all that I have said, this Magistery will become known to you. As for me, how much I have endured on account of this Art, history will reveal to future ages

Melatonin

In humans, melatonin is produced by the pineal gland, a small endocrine gland located in the center of the brain but outside the blood–brain barrier. The melatonin signal forms part of the system that regulates the sleep–wake cycle by chemically causing drowsiness and lowering the body temperature, but it is the central nervous system (specifically the suprachiasmatic nuclei, or SCN) that controls the daily cycle in most components of the paracrine and endocrine systemsrather than the melatonin signal (as was once postulated).

Infants' melatonin levels become regular in about the third month after birth, with the highest levels measured between midnight and 8:00 AM.

In humans, 90% of melatonin is cleared in a single passage through the liver, a small amount is excreted in urine, and a small amount is found in saliva.

Human melatonin production decreases as a person ages. Also, as children become teenagers, the nightly schedule of melatonin release is delayed, leading to later sleeping and waking times.

Light dependence

Production of melatonin by the pineal gland is inhibited by light to the retina and permitted by darkness. Its onset each evening is called the dim-light melatonin onset (DLMO).

It is principally blue light, around 460 to 480 nm, that suppresses melatonin, proportional to the light intensity and length of exposure. Until recent history, humans in temperate climates were exposed to few hours of (blue) daylight in the winter; their fires gave predominantly yellow light. The incandescent light bulb widely used in the twentieth century produced relatively little blue light. Wearing glasses that block blue light in the hours before bedtime may decrease melatonin loss. Kayumov et al. showed that light containing only wavelengths greater than 530 nm does not suppress melatonin in bright-light conditions. Use of blue-blocking goggles the last hours before bedtime has also been advised for people who need to adjust to an earlier bedtime, as melatonin promotes sleepiness.

When used several hours before sleep according to the phase response curve for melatonin in humans, small amounts (0.3 mg) of melatonin shift the circadian clock earlier, thus promoting earlier sleep onset and morning awakening.

Antioxidant

Besides its function as synchronizer of the biological clock, melatonin is a powerful free-radical scavenger and wide-spectrum antioxidant as discovered in 1993. In many less complex life forms, this is its only known function. Melatonin is an antioxidant that can easily cross cell membranes and the blood–brain barrier. This antioxidant is a direct scavenger of radical oxygen and nitrogen species including OH, O2−, and NO. Melatonin works with other antioxidants to improve the overall effectiveness of each antioxidant. Melatonin has been proven to be twice as active as vitamin E, believed to be the most effective lipophilic antioxidant. An important characteristic of melatonin that distinguishes it from other classic radical scavengers is that its metabolites are also scavengers in what is referred to as the cascade reaction. Also different from other classic antioxidants, such as vitamin C and vitamin E, melatonin has amphiphilic properties. When compared to synthetic, mitochodrial-targeted antioxidants (MitoQ and MitoE), melatonin proved to be a better protector against mitochondrial oxidative stress.

Immune system

While it is known that melatonin interacts with the immune system,[49][50] the details of those interactions are unclear. Antiinflammatory effect seems to be the most relevant and most documented in the literature.[51] There have been few trials designed to judge the effectiveness of melatonin in disease treatment. Most existing data are based on small, incomplete clinical trials. Any positive immunological effect is thought to be the result of melatonin acting on high-affinity receptors (MT1 and MT2) expressed in immunocompetent cells. In preclinical studies, melatonin may enhance cytokine production,[52] and by doing this counteract acquired immunodeficiences. Some studies also suggest that melatonin might be useful fighting infectious disease[24] including viral, such as HIV, and bacterial infections, and potentially in the treatment of cancer.[53]

Endogenous melatonin in human lymphocytes has been related to interleukin-2 (IL-2) production and to the expression of IL-2 receptor.[54] This suggests that melatonin is involved in the clonal expansion of antigen-stimulated human T lymphocytes. In rheumatoid arthritis patients, melatonin production has been found increased when compared to age-matched healthy controls.[55]

Although it has not yet been clearly demonstrated whether melatonin increases non-specific immunity with resulting contraindication in autoimmune diseases, an increase in the production of IL-2 and IL-1 was noted in cultured splenocytes.[56]


Dreaming

Some supplemental melatonin users report an increase in vivid dreaming. Extremely high doses of melatonin (50 mg) dramatically increased REM sleep time and dream activity in people both with and without narcolepsy.[57] It has been suggested that nonpolar (lipid-soluble) indolic hallucinogenic drugs emulate melatonin activity in the awakened state and that both act on the same areas of the brain.[57]

Autism

Some individuals with autism spectrum disorders (ASD) may have lower than normal levels of melatonin.[58] A 2008 study found that unaffected parents of individuals with ASD also have lower melatonin levels, and that the deficits were associated with low activity of the ASMT gene, which encodes the last enzyme of melatonin synthesis.[59]

Multiple small studies have demonstrated that 2 to 10 mg of melatonin may benefit children with ASD who have trouble falling asleep and/or maintaining sleep.[60] A small 2011 randomized crossover trial found that the administration of melatonin, when compared to placebo, decreased sleep latency and increased total sleep time, but had no effect on the number of night time awakenings.[61] At this time, no official guidelines exist for the use of melatonin in children with ASD.

Aging

Research has supported the anti-aging properties of melatonin. Younger children hit their peak melatonin production at night, and some researchers believe that the level of melatonin peaks earlier as people get older.[62][63][64] This may explain why older adults go to bed earlier, wake up earlier, and have more sleep problems than children do.[65]

Some studies have shown that melatonin plays a crucial part in the aging process and that it may act as an anti-aging agent when administered to older mice. It has been reported in one study that administration of melatonin in elderly mice may reverse this change in expression of some 13 genes, thus making them similar to those of younger mice.[66] Consuming melatonin may neutralize oxidative damage and delay the neurodegenerative process of aging.[45] When small amounts of melatonin were administered to lab mice, it reduced the oxidative damage caused by aging and delayed the inflammatory process, which in turn increased the longevity of the mice.[67]

Diabetes

Single-nucleotide polymorphisms of the human melatonin MT2 receptor have been linked to an increased risk of developing type 2 diabetes.[68] Furthermore women with low levels of melatonin secretion have been found to more likely to develop type 2 diabetes than women with high levels.[69]
Pediatrics While the packaging of melatonin often warns against use in children, at least one long-term study does assess effectiveness and safety in children. No serious safety concerns were noted in any of the 94 cases studied by means of a structured questionnaire for the parents. With a mean follow-up time of 3.7 years, long-term medication was effective against sleep onset problems in 88% of the cases. Other studies warn against potential side effects

The contradictions between what we're told we should feel and what we actually do feel generates a huge amount of unnecessary suffering.

Remember, you cannot be both young and wise. Young people who pretend to be wise to the ways of the world are mostly just cynics. Cynicism masquerades as wisdom, but it is the farthest thing from it. Because cynics don’t learn anything. Because cynicism is a self-imposed blindness, a rejection of the world because we are afraid it will hurt us or disappoint us. Cynics always say no. But saying “yes” begins things. Saying “yes” is how things grow. Saying “yes” leads to knowledge. “Yes” is for young people. So for as long as you have the strength to, say “yes’.”

People who remember their dreams show different brain activity.
A 2014 study found more spontaneous activity in a part of the brain called the temporo-parietal junction among people who regularly recall their dreams, compared with people who rarely do. The differences weren't just during sleep, but also while study participants were awake. Previous research found that people who remember more dreams also react more to sounds during sleep (and while awake) than people who don't remember many dreams.

Your dreams aren't weird, that is, until you call them weird.
"When you're having the dream, no matter how 'weird' it is -- you're in a poker game with a giant green squirrel and Queen Mary -- it's not weird," says Naiman. "It's only after you wake up and step into the waking world and look at the dream that it seems weird." Comparing "weird" in the dreaming and waking worlds is like comparing dietary customs in two wildly different cultures, he says, making one seem strange in the context of the other. "We need to refrain from exclusively interpreting dreams from the waking world," he says -- which means it's time to toss those dream dictionaries.
“I have not failed 10,000 times, I’ve successfully found 10,000 ways that will not work.” Edison
Gritty kids who succeed do so in spite, not because of, the education system. They follow the path they love. Kids know what they love even when they can't articulate it in some cognitive/symbolic way that makes sense to adults. The problem is that kids just don't want to go and do what/where we think they ought to. Teaching and learning are FAR more than "small class size" -- closer to one on one, and THAT is "too expensive" for an increasingly hyper-conservative, top-down control oriented system. Freeing up the little buggars to chase their curiosities, then selectively providing them with the tools they need at the time they need them? Boy is that a scary notion to all those folks who want to get rid of Darwin and science, let alone art. Sir Ken is spot on.

It's the system, not something missing in the kids.


The passion or determination to continue learning is not the same as the 'grit' to achieve. There is no obvious means to an end when learning something without understanding the benefits of that which is learned. Our education system teaches ideas before there is the rationale to the benefits of applying those ideas. In an indirect way you are insulting the student by forcing them to learn something without giving them a reason why they need to learn it other than grade performance. That is not a relevant goal for some students. There has to be a deeper meaning to the objective of learning to illicit determination, spirit and creativity.

The Essential Habits Of Mentally Strong People

The opposite of depression is not happiness, but vitality, and it was vitality that seemed to seep away from me in that moment."  

"In a world that we don't control, tolerance is obviously an asset," Ryan Holiday, author of the forthcoming The Obstacle Is The Way, told The Huffington Post. "But the ability to find energy and power from what we don't control is an immense competitive advantage."

There's a maxim in the ancient philosophy of Stoicism, "There is no good or bad, there is only perception," which was later echoed in Shakespeare's famous line, "There is nothing either good or bad, but thinking makes it so."
The way we perceive a situation has a tremendous power to either help or harm us. So often, we react emotionally and project negative judgments onto a situation, when the first key to overcoming a challenge is to see things objectively.

Mentally strong people recognize that their entire life plans, and life itself, could be derailed at any moment -- and they don't waste their effort feeling wronged by destiny when things don't quite go their way.

"You could call it being in the zone, you can call it whatever you want, but the idea is that if you're focused exclusively on one thing in front of you, you're not bringing baggage to that situation and you're considering only the variables that matter," says Holiday.
The science has demonstrated that mindfulness really can boost your brain power. Mindfulness practice has been linked with emotional stability, reduced stress and anxiety, and improved mental clarity.

"The idea that everything we do is part of the pursuit of happiness seems to me a really dangerous idea and has led to a contemporary disease in Western society, which is fear of sadness," Mackay writes in The Good Life. "Wholeness is what we ought to be striving for and part of that is sadness, disappointment, frustration, failure; all of those things which make us who we are. Happiness and victory and fulfillment are nice little things that also happen to us, but they don't teach us much."

"In all those different contexts, one factor emerged as a secret to success, and it wasn't social intelligence, good looks, physical health or IQ. It was grit," Duckworth said in a TED talk. "Grit is passion or perseverance for very long-term goals. Grit is having stamina. Grit is sticking with your future, day in and day out -- not just for a day, not just for a month, but for years -- to make that future a reality."

A mentally strong person can say to themselves, "I tried everything I could in this situation, and now I can let it go," says Holiday. Just as important as perseverance is the ability to recognize that you can control only your own actions -- not the results of those actions. Accepting this fact allows us to resign to the things that are beyond our power.

Amor fati. Amor fati is a Latin term that translates to "love of fate," a concept derived from the ancient Greek and Roman Stoic philosophers that later reemerged in the work of Nietzsche. And it's perhaps the single most important key to mental strength. "The idea is that you don't just have to tolerate the things you can't control -- they could be the greatest things that ever happen to you," says Holiday. "You can find the joy in not just accepting, but in embracing the things that happen to you."

"May you always remember that obstacles in the path are not obstacles, they ARE the path."

Conscious Capitalism; think

I know a lot of you, including myself, want to make the best impact on the world as possible and help change it for the better. That abstract and vague goal is hard to put into practice though. What do we do? Buy local, organic produce? Volunteer at a soup kitchen? Help an old lady across the street? All of these are great ways to help make your community united, healthier, and a more loving and nurturing environment for everyone involved, but are they enough? All these practices are fantastic and I don’t discount them as vital to our local community, but in addition what can we do to help our extended community? What can we do to help the human community all over this magnificent planet?

I usually see mentions of Capitalism in a context similar to homophobia, racism, etc. ; it is hated and looked down upon. I do not deny that the way Capitalism has evolved is detrimental to just about every living being on this planet. All you have to do is open your eyes and you will see the effects of its power. Many people ask, in defense of Capitalism, what’s an alternative? Any answer you give will have its pros and cons learned from previous experience. Many say an entirely new system is needed, but where do we start?
I recently became aware of the movement Conscious Capitalism. It’s based on the idea that we do have power in this system that seems so hopeless. This system may fall and we may be left with anarchy, but until that crash, let’s try to take our power back. Let’s give a blood transfusion to rejuvenate the way the system flows. We provide the fuel that runs it, the blood that keeps this machine pumping; money. Where we put our money has an enormous impact on the entire business community, we conduct the currents which give big tidal wave companies power.

We have all seen how the hype about “going green” has produced an onslaught of green products, recycled products, environmentally friendly products, etc. etc. While those words sure seem great while you’re standing in the aisle, how can we be sure these companies are really making a positive impact on the environment they operate in? In that moment we are not asking ourselves some important questions, I am entirely guilty of this too. For starters, what does being green mean to them? How do they treat their employees? Where do the import their products from? What are the living conditions of the wonderful individuals working long days to get this product to our stores? Do they have enough food for the family? Can they send their children to school?
Being green and environmentally friendly should mean more to us than recycling cardboard or yogurt containers. It should mean more than feeling good that we did our part in our purchase. It should mean from source to market, every living being involved in production has the opportunity to flourish and prosper because of our purchasing decision. When we give our money to a company in exchange for their product, we are saying, “I support you. I support your business practices. I support whatever costs you have to cut in order to give me the lowest price possible at whatever expense.” You could even say any wrongdoing is just collateral damage.

I ask you to research just a little bit. Google Conscious Capitalism. Learn where your products are grown, learn about the people nurturing them until we are able to consume them. If you are not happy with the way the process is being run, put your money elsewhere. I’m not asking you to endanger yourself or your family by spending more money on products you can’t afford. I am asking you to learn and understand how your product ends up in your hand. You can choose where to go from there, but the knowledge is truly power. We are demanding a new way of life all over the world and we have a right to know what is the cause of our dissatisfaction.

“We need red blood cells to live (the same way a business needs profits to live), but the purpose of life is more than to make red blood cells (the same way the purpose of business is more than simply to generate profits).”
