By His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Those who are eating animals are animals; they are not human beings. Although they have the form of a human being, they are not considered human beings. When a person is civilized, cultured, then he’s a human being. If he’s not civilized, if he’s not cultured, if he simply has two hands he’s an animal. Civilized culture begins in the Aryan families. Therefore they are called Aryans, which means “advanced.”
