Our conclusion: that anyone who is not Krsna conscious, he is dogs, hogs, camels, asses, that’s all. No brain. Animal. Animal has got brain: how to eat, how to sleep, how to have sex life. So these people, they have got brain for that purpose only. That is animal life. Actually, they do not know what is the aim of life, why people should be educated, why human society should be organized. They do not know.
