1. Udāyī Sutta.– A conversation between Ānanda and Udāyī in the Ghositārāma at Kosambī. Ānanda explains how the Buddha has proved that not only the body but even consciousness is without self. S.iv.166 f.
3. Udāyī Sutta.– Ānanda reports to the Buddha that Udāyī taught a very large following of laymen. The Buddha says that this is not an easy thing to do; he who teaches to a large audience must see, (1) that his talk has a logical reference, (2) that it has reasoning (pariyāya), (3) that it is inspired by kindness (dayā), (4) that it is not for worldly gain, (5) that it causes pain to no one. A.iii.184.
4. Udāyī Sutta.– The Buddha asks Udāyī (Lāḷudāyī according to the Commentary) as to what are the topics of recollection. Three times he asks the question, but Udāyī sits silent. The Buddha then says he knew Udāyī was a fool, and puts the question to Ānanda, who explains five such topics connected with the absorptions (jhāna). A.iii.322‑5.
