There is a class of men who are called śvapaca. Śvapaca means dog-eaters. So the dog-eater is called caṇḍāla, pañcama. The human society is divided into four: first class, second class, third class, fourth class, and pañcama means fifth class. So these dog-eaters, they are considered as the fifth class.
Those who are flesh-eaters, they are fourth class, and those who are vegetarians, they are first class, second class, third class. And those who are animal-food eaters, they are fourth class—and less than that, those who have no distinction of eating any kind of flesh . . . there are certain classes of nation also. They say the Chinese people, they eat anything.
So a man is considered to be situated at a certain status of civilization according to the modes of material nature, and that is manifested by eating, by behaving. Ācāra, vicāra. Ācāra means behavior, and vicāra means judgment. By advancement of education one becomes fixed up to take things by judgment. That is called vicāra. And ācāra means cleanliness or behavior. So ācāra, vicāra. The first-, second- and third-class human being, they are situated in ācāra and vicāra.
