Today I stumbled across a sutta which spoke very nicely to the theme of humility. It is spoken of here as integrity.
AN 4.73 - Sappurisa Sutta: A Person of Integrity
Now, a person endowed with these four qualities can be known as ‘a person of integrity.’ Which four?
There is the case where a person of integrity, when asked, does not reveal another person’s bad points, to say nothing of when unasked. Furthermore, when asked, when pressed with questions, he is one who speaks of another person’s bad points not in full, not in detail, with omissions, holding back. Of this person you may know, ‘This venerable one is a person of integrity.’
Then again, a person of integrity, when unasked, reveals another person’s good points, to say nothing of when asked. Furthermore, when asked, when pressed with questions, he is one who speaks of another person’s good points in full & in detail, without omissions, without holding back. Of this person you may know, ‘This venerable one is a person of integrity.’
