“” Whoso wishes to have insight into the sacred unity, let him consider a flame rising from a burning coal or a burning lamp. He will see first a two-fold light – a bright white, and a black or blue light; the white light is above, and ascends in a direct light, while the blue, or dark light is below, and seems as the chair of the former, yet both are so intimately connected together that they constitute only one flame. The seat, however, formed by the blue or dark light, is again connected with the burning matter which is under it again. The white light never changes its color, it always remains white; but various shades are observed in the lower light, whilst the lowest light, moreover, takes two directions; above, it is connected with the white light, and below with the burning matter. Now this is constantly consuming itself, and perpetually ascends to the upper light, and thus everything merges into a single unity.”
Such were the ancient ideas of the trinity in the unity, as an abstraction. Man, who is the microcosmos of the macrocosmos, or of the archtypal heavenly man, Adam Kadmon, is likewise a trinity; for he is body, soul, and spirit.
“All that is created by the ‘Ancient of the Ancients’ can live and exist only by a male and a female”, says the Sohar. He alone, to whom no one can say, “Thou”, for he is the spirit of the WHITE-HEAD in whom the “THREE HEADS” are united, is uncreated. Out of the subtile fire, on one side of the White Head, and of the “subtile air”, on the other, emanates Shekinah, his veil, (the feminized Holy Ghost). “This air”, says Idra Rabba, “is the most occult, (occultissimus), attribute of the Ancient of the Days. The Ancienter of the Ancienter is the Concealed of the Concealed. All things are Himself, and Himself is concealed in every way. The cranium of the WHITE-HEAD has no beginning, but its end has a shining reflection and a roundness which is our universe.”
“They regard”, says Klenker, “the first-born as man and wife, in so far as his light includes in itself all other lights, and in so far as his spirit of life or breath of life includes all other life spirits in itself.” The kabalistic Shekinah answers to the Ophite Sophia. Properly speaking, Adam Kadmon is the Bythos, but in this emanation-system, where everything is calculated to perplex and place an obstacle to inquiry, he is the Source of Light, the first “primitive man”, and at the same time Ennoia, the Thought of Bythos, the Depth, for he is Pymander.”
