Verse 50: One should not consider the faults of others, nor their doing or not doing good or bad deeds. One should consider only whether one has done or not done good or bad deeds.

The Story of the Ascetic Paveyya

While residing at the Jetavana monastery, the Buddha uttered Verse (50) of this book, with reference to the ascetic Paveyya and a rich lady.

A rich lady of Savatthi had adopted Paveyya, an ascetic, as a son and was looking after his needs. When she heard her neighbours talking in praise of the Buddha, she wished very much to invite him to her house to offer him alms-food. So, the Buddha was invited and choice food was offered. As the Buddha was expressing appreciation (anumodana), Paveyya, who was in the next room, fumed with rage. He blamed and cursed the lady for venerating the Buddha. The lady heard him cursing and shouting and felt so ashamed that she could not concentrate on what the Buddha was saying. The Buddha told her not to be concerned about those curses and threats, but to concentrate only on her own good and bad deeds.

Then the Buddha spoke in verse as follows:

Verse 50: One should not consider the faults of others, nor their doing or not doing good or bad deeds. One should consider only whether one has done or not done good or bad deeds.
At the end of the discourse the rich lady attained Sotapatti Fruition.
