Secret Fire and YHVH

"For our God is a consuming fire." Hebrews 12:29
While alchemy, kabbalah, and astrology have been homogenized in modern esoteric practices to create an almost seamless synthesis, this is not true of earlier periods. Traditionally, alchemy and astrology played almost no role in Jewish kabbalah [5], and while it has been put forward that may Jews were alchemists, and some great alchemists possibly Jews [6], no manuscripts of Jewish alchemical practices seem to exist in any great number. Even the most famed Esch M'saref, or "The Refiner's Fire", is a compilation of material, focusing mainly on gematria, and not a 'chemical' work in itself.
Early kabbalists imagined creation taking place in several stages, from which was generated the anthropomorphic image of the 'primordial man', or Adam Kadmon. This 'first man' was imagined as being crated out of the four-letters of the Divine Name stacked one on top of the other. Yod was the head, Heh, the arms and shoulders, Vau, the spine and sexual organs, and the final Heh, the hips and legs. A host of attributes and qualities came to be associated with each letter, and as a whole, it formed its own school of kabbalistic meditation. By adding other letters, altering combinations, and substituting letters based on numerological equivalents, additional Divine Names, names of archangels, angels, and other spiritual beings were generated.
The oral tradition of Adam Kadmon is similar to that of the Egyptian god Osiris, in that Osiris was dismembered and reconstructed, while Adam "Fell" to pieces, and it is the work of the kabbalist to reconstruct the Original Adam. Each of us is said to be a piece of this original soul, and it is our purpose to find our place in Creation, via kabbalistic methods.
