As ‘Three Wise Monkeys’ of ‘see no evil, hear no evil, speak no evil’ The three monkeys are Mizaru, covering his eyes, who sees no evil; Kikazaru, covering his ears, who hears no evil; and Iwazaru, covering his mouth, who speaks no evil. Sometimes there is a fourth monkey depicted with the three others; the last one, Shizaru, symbolizes the principle of “do no evil”. He may be shown covering his abdomen or genital area, or crossing his arms.
