Prabhupāda: So everything is explained. If anyone wants to take advantage of it, he can take. We have got fifty books like this. Those who are interested in the science and philosophy of Kṛṣṇa consciousness, they can read all these books. Otherwise, one can chant Hare Kṛṣṇa. That will also help. The human civilization means everyone shall try to become first-class man. This is human civilization, not to remain like animals. That attempt is lacking now. Here the civilization is that the dog is jumping or running, and human being is running in a motorcar, and he is thinking he is more civilized than the dog. But the business is running, that's all. The dog is having sex on the street, and the human being is having sex in a very nice decorated apartment, and therefore he is civilized. But the business is the same. The dog is eating on the floor and the human being is eating in a very nice table, nice dish, and therefore he is civilized. But the business is eating. The dog is trying to defend itself by barking or by teeth and jaws, and the human being is trying to defend the society by atom bomb, but the business is defense.
Therefore śāstra says, āhāra-nidrā-bhaya-maithunaṁ ca samanyam etat paśubhir narāṇām (Hitopadeśa): "This business of eating, sleeping, mating and defending is common to the animal and to the man." The man, if he does not understand what he is, why he is suffering this material tribulations, then he remains cats and dogs. The cats and dogs, they cannot question, but human being can question. And he should take the answer from these books of knowledge. That is human life. Otherwise, so far eating, sleeping, sex and defense, that is common for the dogs and man. There is no difference. He is doing in his own way, we are doing in our own way, but the business is the same. So human being must go above these four businesses—the fifth business. The fifth business is how to understand God. Otherwise, the bodily four businesses, that is common. Even an ant, it is also eating. It is going from this place to that place: "Where is a grain of sugar?" And we are also running in car this way and that way: "Where is eating?" The hog is also running: "Where is stool? Where is stool?" So . . . (break) (child makes sounds) Is he chanting mantra? That a small . . .
Jayatīrtha: Yes, he's chanting nicely.
Prabhupāda: (to child) Thank you, Hare Kṛṣṇa. Just see. He is being trained up. Just see how he is taking lesson. So it is possible. So from childhood, if he is trained up, then in future he will become first-class man.
