Buddhism enumerates five stages of gestation that are described in both the Abhidharma-kosha-shastra and the tantras of Great Perfection. The descriptions are very detailed particularly in the tantras of Great Perfection. Despite the fact that the word “cell” was not used in these texts, the writing actually delineated the complex process of cell division (reproduction). Those with a medical background would be very surprised to discover that the depiction is in accord with that of modern medicine. The gestation period between the second instant of conception and right before the development of the six sense organs is designated name and form, which lasts quite a long time.
