AN 3:2 The Fool and the Wise Person
Translated from the Pali by Nyanaponika Thera and Bhikkhu Bodhi
His action marks the fool, his action marks the wise person, O monks. Wisdom shines forth in behaviour.
By three things the fool can be known: by bad conduct of body, speech, and mind.
By three things the wise person can be known: by good conduct of body, speech, and mind.
