(Mv.I.75.1) [141] Now on that occasion Ven. Kumāra [Boy] Kassapa had been given Acceptance twenty years after becoming a fetus. The thought occurred to him, “ It has been laid down by the Blessed One that, ‘an individual less than twenty years old should not be given Acceptance.’ But I have been given Acceptance twenty years after becoming a fetus. Am I accepted or not?”
They reported the matter to the Blessed One.
“When in the mother’s womb the mind first arises and consciousness first appears, in dependence on that is one’s birth.
“I allow that Acceptance be given to one (at least) twenty years after becoming a fetus.”
