This is the basic and fundamental stone of the secret cycles. It shows that the Brâhmans and Tanaïm ... speculated on the creation and development of the world quite in a Darwinian way, both anticipating him and his school in the natural selection, gradual development and transformation of species.(326)

There were old worlds that perished, conquered by the new, etc., etc. The assertion that all the worlds (stars, planets, etc.)—as soon as a nucleus of primordial substance, in the laya (undifferentiated) state, is informed by the freed principles of a just _deceased_ sidereal body—become first comets, and then suns, to cool down to inhabitable worlds, is a teaching as old as the Rishis.

Thus the Secret Books, as we see, distinctly teach an astronomy that would not be rejected even by modern speculation, could the latter thoroughly understand its teachings.

For archaic astronomy and the ancient physical and mathematical sciences expressed views identical with those of Modern Science, and many of far more momentous import. A “struggle for life” and a “survival of the fittest,” in the worlds above and on our planet here below, are distinctly taught. This teaching, however, although it would not be entirely rejected by Science, is sure to be repudiated as an integral whole. For it avers that there are only seven self‐born primordial “Gods,” emanated from the trinitarian One. In other words, it means that all the worlds, or sidereal bodies—always on strict analogy—are formed one from the other, after the primordial manifestation at the beginning of the Great Age is accomplished.

The birth of the celestial bodies in space is compared to a multitude of pilgrims at the Festival of the Fires. Seven ascetics appear on the threshold of the temple with seven lighted sticks of incense. At the light of these the first row of pilgrims light their incense sticks. After which, every ascetic begins whirling his stick around his head in space, and furnishes the rest with fire. Thus with the heavenly bodies. A laya‐ centre is lighted and awakened into life by the fires of another “pilgrim,” after which, the new “centre” rushes into space and becomes a comet. It is only after losing its velocity, and hence its fiery tail, that the Fiery Dragon settles down into quiet and steady life, as a regular respectable citizen of the sidereal family. Therefore it is said:
