So to understand Kṛṣṇa is not very easy thing. Kṛṣṇa says that manuṣyāṇāṁ sahasreṣu, "Out of many millions of millions' person, one tries to become perfect." Who is going to become perfect, especially in this age? Everyone is working like cats and dogs. That's all. Whole day working for eating, sleeping, sex and defense, that's all. They are not manuṣyas. Āhāra-nidrā-bhaya-maithunaṁ ca sāmānyam etat paśubhiḥ narāṇām. Eating... I eat; dog eat. So what is the difference between eating between the dog and me? He is eating according to his taste, I am eating also. The eating business is there in the dog also. Don't think that because you are eating on table, chair, plates, nice preparation... It is eating. People are taking that "Because I am eating on table, chair and nice dish and nice preparation, therefore I am civilized." The śāstra says that it may be different types of taking the eatables, but it is eating. That is even in dog. It does not make any difference. You are not civilized. Similarly sleeping. The dog can sleep on the street without caring for anything. We cannot sleep without nice apartment. So eating, sleeping, mating... Similarly, sex intercourse. Dog has no shame. It can enjoy sex on the street, but we have got some restriction, but the sex is there. Similarly, defense also, bhaya. Bhaya means to take care of fearfulness. That is there in the dog and in you also. It does not make any difference. Because you have got, discovered atomic bomb for defense, it does not mean that you are better than a dog. This is shastric injunction. Because he has to defend himself according to his intelligence and you are defending yourself according to your intelligence.
So this business, four business—eating, sleeping, mating and defending—these are common. Āhāra-nidrā-bhaya-maithunaṁ sāmānyam etat. This is common. Then what is the special advantage of human life? The special advantage is athāto brahma jijñāsā. Jīvasya tattva-jijñāsā. You should be inquisitive to know the value of life, the Absolute Truth. That is... The dog cannot do it. That is the distinction between dog and human being. The human being... In the human form of life there should be inquiry about Brahman, Para-brahman. That is human life. So after inquiring what is Brahman, Para-brahman, janmādy asya yataḥ (SB 1.1.1), the original source of everything, when you attain brahma-jñāna, brahma-bhūtaḥ, that is your perfection, not that to compete with the dog in eating, sleeping, mating and defending. That is not civilization. That is not perfection of life. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). These foolish men, animalistic, dogs and cats, two-legged animals, they do not know what is the aim of life.
