As people upon Earth now again multiplied there was no reason why human souls should not incarnate in their descendants. The earth moon-forces now acted in such a way that under their influence the human bodies became entirely capable of incarnating human souls. The souls who had previously removed to Mars, Jupiter and the other planets were now guided to earth, and there was thus a soul ready for each human being born in the physical line of descent. This went on through long periods so that the immigration of souls to earth corresponded to the increase of human beings. Souls now leaving their bodies at physical death retained the echo of their earthly individuality as a memory in the disembodied state. This memory acted in such a way that whenever a body was born on earth suitable for them, they again incarnated it. Consequently there were among the human descendants some whose souls came from without and who appeared on earth for the first time since its very earliest periods, and there were others whose souls had continually incarnated on the earth. In subsequent periods of earthly evolution the number of young souls appearing for the first time grows ever smaller and smaller, and the reincarnated souls become more and more numerous; yet for long ages the human race was composed of the two types of beings conditioned by these facts. Henceforth man on earth felt himself united with his forefathers through the group-ego which he had in common with them. On the other hand, the experience of the individual ego was all the stronger in the disembodied state between death and a new birth. The souls which entered human bodies from celestial space were in a different position from those which had one or more earthly lives behind them. The former, as souls entering upon the physical earth-life, brought with them only the conditions to which the higher spiritual world and their experiences outside the sphere of earth had subjected them. The others had, by their actions in former lives, added conditions of their own. The fate of the first was determined only by facts lying outside of the new earth-conditions; that of the reincarnate souls is also determined by what they themselves have done in former lives under earthly conditions. Individual human Karma makes its first appearance simultaneously with reincarnation.
