The Stanza now being commented upon opens by speaking of thirty crores, 300,000,000 of years. We may be asked: What could the ancients know of the duration of geological periods, when no modern Scientist or Mathematician is able to calculate their duration with anything like approximate accuracy? Whether they had or had not better means—and it is maintained that they had them as is evidenced by their Zodiacs—still the chronology of the ancient Brâhmans shall now be given as faithfully as possible. The Chronology of the Brâhmans. No greater riddle exists in Science, no problem is more hopelessly insoluble, than the question: How old—even approximately—are the Sun and Moon, the Earth and Man? What does Modern Science know of the duration of the Ages of the World, or even of the length of Geological Periods? Nothing; absolutely nothing. If one turns to Science for chronological information, one is told by those who are straightforward and truthful, as for instance Mr. Pengelly, the eminent Geologist, “We do not know.”(143) One will learn that, so far, no trustworthy numerical estimate of the ages of the World and Man could be made, and that both Geology and Anthropology are at sea. Yet when a student of Esoteric Philosophy presumes to bring forward the teachings of Occult Science, he is at once sat upon. Why should this be so, since, when reduced to their own physical methods, the greatest Scientists have failed to arrive even at an approximate agreement? It is true that Science can hardly be blamed for it. Indeed, in the Cimmerian darkness of the prehistoric ages, the explorers are lost in a labyrinth, whose great corridors are doorless, allowing no visible exit into the archaic past. Lost in the maze of their own conflicting speculations, rejecting, as they have always done, the evidence of Eastern tradition, without any clue, or one single certain milestone to guide them, what can Geologists or Anthropologists do but pick up the slender thread of Ariadne where they first perceive it, and then proceed at perfect random? Therefore we are first told that the farthest date to which documentary record extends is now generally regarded by Anthropology as but “the earliest distinctly visible point of the pre‐historic period”—in the words of the writer of the article in the _Encyclopædia Britannica_. At the same time it is confessed that “beyond that period stretches back a vast indefinite series of pre‐historic ages.”
