The Buddha (6th-5th century BCE)
“Regard the person who sees your faults
as a revealer of treasures.
Associate with that skilled person
as one who is wise, who speaks reprovingly
Keeping company with such a person,
things get better, not worse.”
- The Dhammapada (Verses on the Way, Chapter 6), recorded in the 3rd century BCE. Translation by Glenn Wallis, 2004.
