長阿含經 22.p73

22.p73

The Buddha said, “Good, good! As you’ve said, having precepts is having wisdom, and having wisdom is having precepts. Precepts purify wisdom, and wisdom purifies precepts. Śroṇatāṇḍya, it’s like when someone washes their hands: The right and left hand need each other. The left hand washes the right hand, and the right hand washes the left hand. These things are likewise. Having wisdom is having precepts, and having precepts is having wisdom. Precepts purify wisdom, and wisdom purifies precepts. Priest, I say someone endowed with precepts and wisdom is called a monk.”
