THE FIFTH KEY

The Fifth Key includes the Fermentation of the Stone with the perfect body, to make therof the medicine of the Third order. I will say nothing in particular of the operation of the Third work; except that the Perfect Body is a necessary leaven of Our Paste. And that the Spirit ought to make the union of the paste with the leaven in the same manner as water moistens meal, and dissolves the leaven to compose a fermented paste fit to make bread. This comparison is very proper; Hermes first made it, saying, that as a paste cannot be fermented without a ferment; so when you shall have sublimed, cleansed and separated the foulness from the Faeces, and would make the conjunction, put a ferment to them and make the water earth, that the paste may be made a ferment; which repeats the instruction of the whole work, and shows, that just so as the whole lump of the paste becomes leaven, by the action of the ferment which has been added, so all the philosophic confection becomes, by this operation, a leaven proper to ferment a new matter, and to multiply it to infinity.

If you observe well how bread is made, you will find the proportions also, which you ought to keep among the matters which compose our philosophical paste. Do not the bakers put more meal than leaven, and more water than the leaven and the meal? The laws of Nature are the rules you ought to follow in the practice of our magistery. I have given you, upon the principal point, all the instructions which are necessary for you, so that it would be superfluous to tell you more of it; particularly concerning the last operations, about which the Adepts have been less reserved than at the First, which are the foundations of the Art.
