To be all animal is not good; and to be all angel is not good either, because we are made with an animal body which needs to eat, drink, and sleep, and whose senses have a thousand needs. We should keep those animal attributes that are harmless, and give up those that are harmful. To eat is not bad and to drink is not bad, but to snatch the food from another's plate when we already have food on our own, that is a bad thing.
