Bankei Yotaku was a Japanese Rinzai Zen master in the Edo period. When he passed away, a blind man who lived near the monastery said:

“Since I am blind, I cannot watch a person’s face, so I must judge his character by the sound of his voice. Ordinarily, when I hear someone congratulate another upon his happiness or success, I also hear a secret tone of envy. When condolence is expressed for the misfortune of another, I hear pleasure and satisfaction, as if the one condoling was really glad there was something left to gain in his own world.

“In all my experience, however, Bankei’s voice was always sincere. Whenever he expressed happiness, I heard nothing but happiness, and whenever he expressed sorrow, sorrow was all I heard.”
