Sāriputta asks about support “after twenty years”

Reliability undetermined

The Chinese Shelifu wen jing (Sutra of 's Questions) records Sāriputta asking the Buddha why, in the first twenty years of the Buddha's life as a Buddha, the disciples had no regular support and accepted whatever came, whereas after twenty years regular support became plentiful. The Buddha answers with the story of the past-life deeds of a householder's son, Fenruoduoluo.

Different Accounts

This passage is found only in the Shelifu wen jing; which school this sutra belongs to has not yet been settled here, and it serves only as supplementary reference.

Dating

After Year 21 after the Awakening (the Buddha aged fifty-five or more). The text states “after twenty years” but does not say which year; converting this into a year after the Awakening is only an estimate.
