All this, teaches the Hidden Science, is but the temporary reflection, the shadow of the eternal ideal prototype in Divine Thought; the word “Eternity,” note well again, standing here only in the sense of “Æon,” as lasting throughout the seemingly interminable, but still limited cycle of activity, called by us Manvantara. For what is the real esoteric meaning of Manvantara, or rather a Manu‐antara? It means, literally, “between two Manus,” of whom there are fourteen in every Day of Brahmâ, such a Day consisting of 1,000 aggregates of four Ages, 1,000 “Great Ages” or Mahâyugas. Let us now analyse the word or name Manu. Orientalists in their dictionaries tell us that the term “Manu” is from the root _man_, “to think”; hence “the thinking man.” But, esoterically, every Manu, as an anthropomorphized patron of his special cycle (or Round), is but the personified idea of the “Thought Divine” (as the Hermetic Pymander); each of the Manus, therefore, being the special god, the creator and fashioner of all that appears during his own respective cycle of being or Manvantara. Fohat runs the Manus’ (or Dhyân Chohans’) errands, and causes the ideal prototypes to expand from within without—that is, to cross gradually, on a descending scale, all the planes, from the noumenal to the lowest phenomenal, to bloom finally on the last into full objectivity—the acme of Illusion, or the grossest matter. 2. THE VIBRATION SWEEPS ALONG, TOUCHING(93) WITH ITS SWIFT WING THE WHOLE UNIVERSE AND THE GERM THAT DWELLETH IN DARKNESS, THE DARKNESS THAT BREATHES(94) OVER THE SLUMBERING WATERS OF LIFE. The Pythagorean Monas is also said to dwell in solitude and “Darkness” like the “Germ.” The idea of the Breath of Darkness moving over “the slumbering Waters of Life,” which is Primordial Matter with the latent Spirit in it, recalls the first chapter of _Genesis_. Its original is the Brâhmanical Nârâyana (the Mover on the Waters), who is the personification of the Eternal Breath of the unconscious All (or Parabrahaman) of the Eastern Occultists. The Waters of Life, or Chaos—the female principle in symbolism—are the vacuum (to our mental sight), in which lie the latent Spirit and Matter. This it was that made Democritus assert, after his instructor Leucippus, that the primordial principles of all were atoms and a vacuum, in the sense of space, but not of empty space, for “Nature abhors a vacuum,” according to the Peripatetics and every ancient philosopher. In all Cosmogonies “Water” plays the same important part. It is the base and source of material existence. Scientists, mistaking the word for the thing, understand by it the definite chemical combination of oxygen and hydrogen, thus giving a specific meaning to a term used by Occultists in a generic sense, and which is employed in Cosmogony with a metaphysical and mystical meaning. Ice is not water, neither is steam, although all three have precisely the same chemical composition.
