• Pindapātapārisuddha Sutta

Preached at Veluvana in Rājagaha. Sāriputta visits the Buddha and tells him that most of his time is spent aloof. The Buddha praises him and says that all monks should practise constant review and self questioning when they go begging for alms, and should rid themselves of the evils they have and develop those virtues they already possess. M.iii.293 ff.
