The Buddha was once staying at the Migáramátupásáda, and on the day of the pavárana he summoned the five hundred arahants who were with him and asked if they had any fault to find with him.
Sáriputta, speaking for them, uttered the Buddha's praises, and the Buddha, in his turn, spoke of Sáriputta's greatness and of the blamelessness of the arahants. Thereupon Vangísa, also present, extolled the Buddha in verse. S.i.190f.; also Thag.vs.1234ff.
