Thus we have all that the Krishna impulse signifies incarnated in the body of the Luke Jesus child. What was there embodied is related to the forces that are asleep in every child in their sublime purity and innocence, until they awaken as the sex-forces. In this child they can manifest themselves and be active until the age of puberty when man ordinarily becomes sexually mature. But the body of this child that had been taken from common humanity would no longer have been adapted to the forces related to the innocent sex-forces in the child. Thus the soul in the other Jesus child, which was the soul of Zarathustra, that had passed through many incarnations and reached its eminence by hard work and special striving, passed over into the body of the Luke Jesus child, and from then on dwelt in that body.
