1. Udāyī Sutta.-A conversation between Ananda and Udāyī in the Ghositārāma at Kosambī. Ananda explains how the Buddha has proved that not only the body but even consciousness is without self. S.iv.166f.
2. Udāyī Sutta.-Udāyī visits the Buddha at Desaka (?) in the Sumbha country and describes how he had realised Nibbāna by developing the bojjhangas. S.v.89f.
3. Udāyī Sutta.-Ananda reports to the Buddha that Udāyī preached to a very large following of laymen. The Buddha says that this is not an easy thing to do; he who preaches 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 (Lāludāyī 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 Ananda, who explains five such topics connected with the jhānas. A.iii.322-5.
