(_c_) Man’s organism was adapted in every Race to its surroundings. The first Root‐Race was as ethereal as ours is material. The progeny of the Seven Creators, who evolved the Seven Primordial Adams,(86) surely required no purified gases to breathe and live upon. Therefore, however strongly the impossibility of this teaching may be urged by the devotees of Modern Science, the Occultist maintains that the case was as stated _æons of years_ before even the evolution of the Lemurian, the first physical man, which took place 18,000,000 years ago. Archaic Scripture teaches that at the commencement of every local Kalpa, or Round, the Earth is reborn, and preliminary evolution is described in one of the _Books of Dzyan_ and the Commentaries thereon in this wise: “_As the human Jîva [Monad], when passing into a new womb, gets recovered with a new body, so does the Jîva of the Earth; it gets a more perfect and solid covering with each Round after reëmerging once more from the matrix of space into objectivity._” This process is attended, of course, by the throes of the new birth, or geological convulsions. The only reference to it is contained in one verse of the volume of the _Book of Dzyan_ before us, where it says: 4. AFTER GREAT THROES SHE(87) CAST OFF HER OLD THREE AND PUT ON HER NEW SEVEN SKINS, AND STOOD IN HER FIRST ONE. This refers to the growth of the Earth, whereas in the Stanza treating of the First Round it is said in the Commentary: “_After the changeless [Avikâra] immutable Nature [Essence, Sadaikarûpa] had awakened and changed [differentiated] into [a state of] causality [Avyakta], and from cause [Kârana] had become its own discrete effect [Vyakta], from invisible it became visible. The smallest of the small [the most atomic of atoms, or anîyânsam anîyasâm] became one and the many [Ekânekarûpa]; and producing the Universe produced also the fourth Loka [our Earth] in the garland of the seven lotuses. The Achyuta then became the Chyuta._”(88) The Earth is said to cast off “her old _three_” Skins, because this refers to the three preceding Rounds she has already passed through; the present being the Fourth Round out of the seven. At the beginning of every new Round, after a period of Obscuration, the Earth—as do also the other six “Earths”—casts off, or is supposed to cast off, her old Skins as the Serpent does; therefore she is called in the _Aitareya‐Brâhmana_ the Sarpa‐Râjnî, the “Queen of the Serpents,” and “the mother of all that moves.” The “Seven Skins,” in the first of which she now stands, refer to the seven geological changes which accompany and correspond to the evolution of the Seven Root‐Races of Humanity.
