Prabhupāda: He is eternal but because he is influenced by the mind, desires, and the senses, sense enjoyment, he is struggling. This is it, a struggle. So when he is too much fatigued, Kṛṣṇa comes and gives you good counsel. "You rascal give up these all desires. Surrender to Me, I give you protection." But he'll not do that. And if he agrees then anyābhilāṣitā-śūnyam (Brs. 1.1.11), all material desires, zero. Then bhakti begins. And if you have got a little pinch of material desires, then you have to accept different types of body. It will create, naturally. Kāraṇaṁ guṇa-saṅgo 'sya (BG 13.22). He is desiring under the influence of particular modes of nature, and he's getting body.
Harikeśa: One has to be very careful.
Prabhupāda: Yes. Otherwise even a devotee like Bhārata Mahārāja, he had to accept the body of a deer. A little careless. Then nature's law will act. Hm? If you do not become cautious and if you infect the smallpox disease, you have to suffer. Therefore a civilized man takes process, caution, "Oh there is smallpox disease, I shall not go there. Or if I go there, I must take vaccine." This is human civilization, caution. And if you are animal, you do not know. So human life means not animal life. Very reasonable, very cautious, educated, cultured, that is human life. Not animal life. Drink like animal, or eat like animal, have sex life like animal. Freedom, animal has got all freedom. So that freedom is not allowed to the human beings. That is civilization. The same example. The animal has got freedom and you'll see in Indian market, vegetable market, some cow comes and eats, takes so many vegetables and eats, but he's not going to the court. But if you take one small piece of chili without, then you'll go to the court. So therefore, law is meant for human beings, not for the animals. Those who want to be free, they are animals. So-called freedom means animalism. That is not humanism. Humanism means to follow the rules and regulations and the laws, and then he is human being. Because law is meant for the human being, not for the animals. And when you come out from your home, immediately the law is keep to the right. And if you violate, immediately you go to the law. But a dog, he doesn't care. If you say, "A dog does not obey this law," that is no excuse. You are human being. If you don't obey then you go to jail. So many animals are on the street naked, they're having sex life, naked. You do, immediately you'll be prosecuted. Why? Because you are a human being. You have to restrain. Even if you like. Just like the Hawaii University students, "What is the wrong to become a dog?" So if you think like that then you become a dog, nature is ready to give you a dog's body. That is (Sanskrit). He's thinking, "The dog's life is very nice. This liberation of sex life on the street." "Alright, you take dog's body."
