mn79:7.1 “Udāyī, someone who can recollect their many kinds of past lives, with features and details, might ask me a question about the first beginning, or I might ask them a question about the first beginning.
mn79:7.2 And they might satisfy me with their answer, or I might satisfy them with my answer.
mn79:7.3 Someone who, with clairvoyance that is purified and superhuman, understands how sentient beings pass on according to their deeds might ask me a question about the final end, or I might ask them a question about the final end.
mn79:7.4 And they might satisfy me with their answer, or I might satisfy them with my answer.
mn79:7.5 Nevertheless, Udāyī, leave aside the first beginning and the final end.
mn79:7.6 I shall teach you the Dhamma:
mn79:7.7 ‘When this exists, this comes to be; due to the arising of this, this arises.
mn79:7.8 When this doesn’t exist, that is not; due to the cessation of this, that ceases.’”
