Lecture VI
And now remind yourselves of the development of an individual human being: from birth until about the seventh year it is paramountly the physical body that is in process of development, during the next seven years, from the second dentition until puberty, the etheric body; and only then does the free development of the astral body begin. In the case of the physical and etheric bodies prepared for Zarathustra through the generations beginning with Abraham, this process of development was to reach culmination and into these bodies Zarathustra was to descend in the new incarnation. But when the development of the etheric body had reached its conclusion, what had been prepared for him was no longer adequate and he had now to proceed to the development of the astral body.
