Those who are aware that the “Great Flood,” which was connected with the sinking of an entire Continent (save only a few islands) could not have happened so far back as 18,000,000 years ago, and that Vaivasvata Manu is the Indian Noah connected with the Matsya, or the Fish, Avatâra of Vishnu, may feel perplexed at the apparent discrepancy between the facts stated and the chronology previously given. But there is no discrepancy in truth. The reader is asked to turn to _The Theosophist_ of July, 1883, for by studying the article therein, on “The Septenary Principle in Esotericism,” the whole question can be explained to him. It is in the explanation there given, I believe, that the Occultists differ from the Brâhmans. For the benefit of those, however, who may not have _The Theosophist_ of that date to hand, a passage or two may now be quoted from it: Who was Manu, the son of Svâyambhuva? The Secret Doctrine tells us that _this_ Manu was no man, but the representation of the first human races, evolved with the help of the Dhyân Chohans (Devas), at the beginning of the First Round. But we are told in his _Laws_ (i. 80) that there are fourteen Manus for every Kalpa, or “interval from creation to creation”—read rather interval from one _minor_ Pralaya to another(687)—and that “in the present divine age, there have been as yet _seven_ Manus.” Those who know that there are seven Rounds, of which we have passed three, and are now in the Fourth; and who are taught that there are seven Dawns and seven Twilights, or fourteen Manvantaras; that at the beginning of every Round and at the end, and on, and between, the planets [Globes] there is an “awakening to _illusive_ life,” and an “awakening to _real_ life”; and that, moreover, there are Root‐ Manus, and what we have to clumsily translate as Seed‐Manus—_the seeds for the human races of the forthcoming_ Round (or the Shishtas—the surviving fittest(688); a mystery divulged only to those who have passed their third degree in Initiation)—those who have learned all this will be better prepared to understand the meaning of the following. We are told in the Hindû Sacred Scriptures that, “The first Manu produced _six_ other Manus [_seven_ primary Manus in all], and these produced in their turn each seven other Manus”(689) (_Bhrigu_, i. 61‐63)—the production of the latter standing in the Occult treatises as 7 x 7. Thus it becomes clear that Manu—the last one, the Progenitor of our Fourth‐Round Humanity—must be the _seventh_, since we are on our Fourth Round,(690) and there is a _Root_‐Manu at Globe A, and a _Seed_‐Manu at Globe G. Just as each planetary Round commences with the appearance of a Root‐Manu (Dhyân Chohan) and closes with a Seed‐Manu, so a Root‐ and a Seed‐Manu appear respectively at the beginning and the termination of the human period on any
