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.
