It was, then, the animal-men, the lowest class of human beings of the Moon-chain, who established the forms in the first round of the Earth-chain. Pressing closely after them were the highest of the lunar animal kingdom, who were soon ready to occupy the forms which had just been made. In the second journey round the seven globes of the Earth-chain, the animal-men who had been the most backward of the lunar humanity were leaders of this terrene humanity, the highest of the moon-animals making its less developed grades. The same thing went on in the third round of the Earth-chain, more and more of the lunar animals attaining individualization and joining the human rank, until in the middle of that round on this very globe D which we call the Earth, a higher class of human beings--the Second Order of Moon-men--descended into incarnation and at once took the lead. When we come to the fourth, our present round, we find the First Order of the Moon-men pouring in upon us--all the highest and the best of the lunar humanity who had only just fallen short of success. Some of those who had already, even on the Moon, entered upon the Path soon attained its end, became Adepts and passed away from the Earth. Some few others who had not been quite so far advanced have attained Adeptship only comparatively recently--that is, within the last few thousand years, and these are the Adepts of the present day. We, who find ourselves in the higher races of humanity now, were several stages behind Them, but the opportunity lies before us of following in Their steps if we will. The evolution of which we have been speaking is that of the Ego himself, of what might be called the soul of man; but at the same time there has been also an evolution to the body. The forms built in the first round were very different from any of which we know anything now. Properly speaking, those which were made on our physical earth can scarcely be called forms at all, for they were constructed of etheric matter only, and resembled vague, drifting and almost shapeless clouds. In the second round they were definitely physical, but still shapeless and light enough to float about in currents of wind. Only in the third round did they begin to bear any kind of resemblance to man as we know him today. The very methods of reproduction of those primitive forms differed from those of humanity today, and far more resembled those which we now find only in very much lower types of life. Man in those early days was androgynous, and a definite separation into sexes took place only about the middle of the third round. From that time onward until now the shape of man has been steadily evolving along definitely human lines, becoming smaller and more compact than it was, learning to stand upright instead of stooping and crawling, and generally differentiating itself from the animal forms out of which it had been evolved.
