"Since I cannot see a person’s face, I must judge his sincerity by his voice. Usually when I hear someone congratulate a friend on some success, I also hear envy in his voice, and when I hear expressions of condolence, I hear a secret tone of pleasure. Not so with Bankei; when he expressed happiness, his voice was completely happy, and when he expressed sadness, sadness was all I heard."
a blind man’s eulogy to Zen Master Bankei (1622-1693)
