There I shall give myself into bondage, to redeem all the world from the forest of purgatory, from
rebirth as beasts, from the realm of death.
Since the idea of
rebirth was generally accepted by Buddhists
as well
as by all other people in India, and since birth was not limited to the human level, it was possible to have Buddha born to fit any ancient tale of India, whether of
beast or people — and this was actually done.
