AN 5.198
Vaca Sutta: A Statement
translated from the Pali by
Thanissaro Bhikkhu

"Monks, a statement endowed with five factors is well-spoken, not ill-spoken. It is blameless & unfaulted by knowledgeable people. Which five?

"It is spoken at the right time. It is spoken in truth. It is spoken affectionately. It is spoken beneficially. It is spoken with a mind of good-will.

"A statement endowed with these five factors is well-spoken, not ill-spoken. It is blameless & unfaulted by knowledgeable people."
