Summary
s.1In The Teaching to the Venerable Nanda on Entry into the Womb, the Buddha gives a detailed account to his half-brother Nanda of the thirty-eight weeks of human gestation. The sūtra explains conception in terms of how the antarābhava (the being in the state between death in one life and birth in the next) enters the womb, and details the physical composition of the embryo, the suffering of the newborn being, and the miseries experienced over the course of a lifetime. Including as it does the most comprehensive ancient Indian account of gestation, it was an important source for embryology in Tibetan medicine.
s.1《為長老難陀說入胎經》中，佛陀詳細地向其同父異母的兄弟難陀講述人類懷孕的三十八週。經文以中有（死後到下一次生命之間的存在狀態）如何進入胎藏來解釋受孕，並詳細說明胎兒的物質組成、新生兒的痛苦，以及一生中所經歷的各種苦難。由於這部經文包含了最全面的古印度懷孕生殖學說，它成為藏醫胚胎學的重要來源。
