It is, then, the Moon that plays the largest and most important part, as well in the formation of the Earth itself, as in the peopling thereof with human beings. The Lunar Monads, or Pitris, the ancestors of man, become in reality man himself. They are the Monads, who enter on the cycle of evolution on Globe A, and who, passing round the Chain of Globes, evolve the human form, as has just been shown. At the beginning of the human stage of the Fourth Round on this Globe, they “ooze out” their astral doubles, from the “ape‐like” forms which they had evolved in the Third Round. And it is this subtle, finer form, which serves as the model round which Nature builds physical man. These Monads, or Divine Sparks, are thus the Lunar Ancestors, the Pitris themselves; for these Lunar Spirits have to become “men,” in order that their Monads may reach a higher plane of activity and self‐consciousness, _i.e._, the plane of the Mânasa‐Putras, those who endow the “senseless” shells, created and informed by the Pitris, with “mind,” in the latter part of the Third Root‐Race.

In the same way, the Monads, or Egos, of the men of the Seventh Round of our Earth, after our own Globes A, B, C, D, etc., parting with their life‐ energy, will have informed, and thereby called to life, other laya‐ centres, destined to live and act on a still higher plane of being—in the same way will the Terrene Ancestors create those who will become their superiors.

It now becomes plain, that there exists in Nature a triple evolutionary scheme for the formation of the three _periodical_ Upâdhis; or rather three separate schemes of evolution, which in our system are inextricably interwoven and interblended at every point. These are the Monadic (or Spiritual), the Intellectual, and the Physical Evolutions. These three are the finite aspects, or the reflections on the field of Cosmic Illusion, of Âtmâ, the seventh, the One Reality.

1. The Monadic, as the name implies, is concerned with the growth and development into still higher phases of activity of the Monads, in conjunction with:

2. The Intellectual, represented by the Mânasa‐Dhyânis (the Solar Devas, or the Agnishvatta Pitris), the “givers of intelligence and consciousness” to man, and:
