The Secret Book:
(41) Let therefore the spirit of our living water be, with all care and industry, fixed with sol and luna; for they being converted into the nature of water become dead, and appear like to the dead; from thence afterwards being revived, they increase and multiply, even as do all sorts of vegetable substances; it suffices then to dispose the matter sufficiently without, because that within, it sufficiently disposes itself for the perfection of its work. For it has in itself a certain and inherent motion, according to the true way and method, and a much better order than it is possible for any man to invent or think of. For this cause it is that you need only prepare the matter, nature herself will perfect it; and if she be not hindered by some contrary thing, she will not overpass her own certain motion, neither in conceiving or generating, nor in bringing forth.
(42) Wherefore, after the preparation of the matter, beware only lest by too much heat or fire, you inflame the bath, or make it too hot; secondly, take heed lest the spirit should exhale, lest it hurt the operator, to wit, lest it destroy the work, and induce many informities, as trouble, sadness, vexation, and discontent. From these things which have been spoken, this axiom is manifest, to wit, that he can never know the necessary course of nature, in the making ot generating of metals, who is ignorant of the way of destroying them. You must therefore join them together that are of one consanguinity or kindred; for like natures do find out and join with their like natures, and by putrifying themselves, and mix together and mortify themselves. It is needful therefore to know this corruption and generation, and the natures themselves do embrace one another, and are brought to a fixity in a slow and gentle fire; how like natures rejoiceth with like natures; and how they retain one another and are converted into a white consistency.
(43) This white substance, if you will make it red, you must continually decoct it in a dry fire till it be rubified, or become red as blood, which is nothing but water, fire, and true tincture. And so by a continual dry fire, the whiteness is changed, removed, perfected, made citrine, and still digested till it become to a true red and fixed color. And consequently by how much more it is heightened in color, and made a true tincture of perfect redness. Wherefore with a dry fire, and a dry calcination, without any moisture, you must decoct this compositum, till it be invested with a most perfect red color, and then it will be the true and perfect elixir.
(44) Now if afterwards you would multiply your tincture, you must again resolve that red, in new and fresh dissolving water, and then by decoctions first whiten, and then rubify it again, by the degrees of fire, reiterating the first method of operating in this work. Dissolve, coagulate, and reiterate the closing up, the opening and multiplying in quantity and quality at your own pleasure. For by a new corruption and generation, there is introduced a new motion. Thus we can never find an end if we do always work by reiterating the same thing over and over again, viz. by solution and coagulation, by the help of our dissolving water, by which we dissolve and congeal, as we have formerly said, in the beginning of the work. Thus also is the virtue thereof increased, and multiplied both in quantity and quality; so that if after the first course of the operation you obtain a hundred fold; by the second fold you will have a thousand fold; and by the third; ten thousand fold increase. And by pursuing your work, your projection will come to infinity, tinging truly and perfectly, and fixing the greatest quantity how much soever. Thus by a thing of small and easy price, you have both color, goodness, and weight.
(45) Our fire then and azoth are sufficient for you: decoct, reiterate, dissolve, congeal, and continue this course, according as you please, multiplying it as you think good, until your medicine is made fusible as wax, and has attained the quantity and goodness or fixity and color you desire. This then is the compleating of the whole work of our second stone (observe it well) that you take the perfect body, and put it into our water in a glass vesica or body well closed, lest the air get in or the enclosed humidity get out. Keep it in digestion in a gentle heat, as it were of a balneum, and assiduously continue the operation or work upon the fire, till the decoction and digestion is perfect. And keep it in this digestion of a gentle heat, until it be purified and re-solved into blackness, and be drawn up and sublimed by the water, and is thereby cleaned from all blackness and impurity, that it may be white and subtle. Until it comes to the ultimate or highest purity of sublimation, and utmost volatility, and be made white both within and without: for the vulture flying in the air without wings, cries out that it might get up upon the mountain, that is upon the waters, upon which the spiritus albus or spirit of whiteness is born. Continue still a fitting fire, and that spirit, which is the subtle being of the body, and of the mercury will ascend upon the top of the water, which quintessence is more white than the driven snow. Continue yet still, and towards the end, increase the fire, till the whole spiritual substance ascend to the top. And know well, that whatsoever is clear, white-pure and spiritual, ascends in the air to the top of the water in the substance of a white vapor, which the philosophers call their virgin milk.
(46) It ought to be, therefore, as one of the Sybills said, that the son of the virgin be exalted from the earth, and that the white quintessence after its rising out of the dead earth, be raised up towards heaven; the gross and thick remaining in the bottom, of the vessel and the water. Afterwards, the vessel being cooled, you will find in the bottom the black feces, scorched and burnt, which separate from the spirit and quintessence of whiteness, and cast them away. Then will the argent vive fall down from our air and spirit, upon the new earth, which is called argent vive sublimed by the air or spirit, whereof is made a viscous water, pure and white. This water is the true tincture separated from all its black feces, and our brass or latten is prepared with our water, purified and brought to a white color. Which white color is not obtained but by decoction and coagulation of the water; decoct, therefore, continually, wash away the blackness from the latten, not with your hands, but with the stone, or the fire, or our second mercurial water which is the true tincture. This separation of the pure from the impure is not done with hands, but nature herself does it, and brings it to perfection by a circular operation.
(47) It appears then, that this composition is not a work of hands, but a change of the natures; because nature dissolves and joins itself, sublimes and lifts itself up, and grows white, being separated from the feces. And in such a sublimation the more subtle, pure, and essential parts are conjoined; for that with the fiery nature or property lifts up the subtle parts, it separates always the more pure, leaving the grosser at the bottom. Wherefore your fire ought to be gentle and a continual vapor, with which you sublime, that the matter may be filled with spirit from the air, and live. For naturally all things take life from the inbreathing of the air; and so also our magistery receives in the vapor or spirit, by the sublimation of the water.
(48) Our brass or latten then, is to be made to ascend by the degrees of fire, but of its own accord, freely, and without violence; except the body therefore be by the fire and water broken, or dissolved, and attenuated, until it ascends as a spirit, or climbs like argent vive, or rather as the white soul, separated from the body, and by sublimation diluted or brought into a spirit, nothing is or can be done. But when it ascends on high, it is born in the air or spirit, and is changed into spirit; and becomes life with life, being only spiritual and incorruptible. And by such an operation it is that the body is made spirit, of a subtle nature, and the spirit is incorporated with the body, and made one with it; and by such a sublimation, conjunction, and raising up, the whole, both body and spirit are made white.
(49) This philosophical and natural sublimation therefore is necessary which makes peace between, or fixes the body and spirit, which is impossible to be done otherwise, than in the separation of these parts. Therefore it behoves you to sublime both, that the pure may ascend, and the impure may descend, or be left at the bottom, in the perplexity of a troubled sea. And for this reason it must be continually decocted, that it may be brought to a subtle property, and the body may assume, and draw to itself the white mercurial soul, which it naturally holds, and suffers not to be separated from it, because it is like to it in the nearness of the first pure and simple nature. From these things it is necessary, to make a separation by decoction, till no more remains of the purity of the soul, which is not ascended and exalted to the higher part, whereby they will both be reduced to an equality of properties, and a simple pure whiteness.
(50) The vulture flying through the air, and the toad creeping upon the ground, are the emblems of our magistery. When therefore gently and with much care, you separate the earth from the water, that is from the fire, and the thin from the thick, then that which is pure will separate itself from the earth, and ascend to the upper part, as it were into heaven, and the impure will descend beneath, as to the earth. And the more subtle part in the superior place will take upon it the nature of a spirit, and that in the lower place, the nature of an earthy body. Wherefore, let the white property with the more subtle part of the body, be by this operation, made to ascend leaving the feces behind, which is done in a short time. For the soul is aided by her associate and fellow, and perfected by it. My mother, saith the body, has begotten me, and by me she herself is begotten; now after I have taken from her, her flying she after an admirable manner becomes kind and nourishing, and cherishing the son whom she has begotten till he come to a ripe or perfect age.
