So this varṇāśrama-dharma means cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13), from the animal position of the human being, to bring him to the human position. That is varṇāśrama-dharma. Just (as in) school (or) college, to become graduate means to become distinguished from the fools and rascals. Similarly, human being does not mean the struggle for existence as the one big fish is eating another small fish, another is... No, no, that is not human. That is natural, but you have to rectify the natural position for the..., for realization of the utmost aim of life. That is human life. Not to treat like animals. Sa eva go-kharaḥ (SB 10.84.13). So that spiritual consciousness begins when one understands that he is soul; he is not this body, he is spirit soul, ahaṁ brahmāsmi. Brahman means the spirit soul. And there human civilization begins. Otherwise, anārya, anārya-juṣṭam. Kṛṣṇa, when Arjuna was declining to fight, He chastised him that "This denial is anārya-juṣṭam. It is befitting for the anārya, those who are not advanced. One must do his duty. You are a kṣatriya, your duty is to fight to give protection to the citizen, so why you are denying this?"
So here the example is given, jalaukasāṁ jale yadvan mahāntaḥ adanti. Adanti means swallows up. Similarly, when the Yadus became very powerful... Because they are descendants of Kṛṣṇa, who can be...? So they were fighting anywhere, conquering anywhere, and everywhere they were victorious. So that was bhū-bhārān. Bhū-bhārān means burden of the world. When one becomes extravagant and misuses his power, that is burden of the world. You cannot misuse your... You get power by the grace of God, by grace of Kṛṣṇa. If you misuse it, then you become a burden, a burden. As soon as there is burden, then it is dharmasya glāniḥ. Kṛṣṇa says, yadā yadā hi dharmasya glānir bhavati (BG 4.7). As soon as there is a misuse of power, tadātmānaṁ sṛjāmy aham, He comes. So Yadu-vaṁśa, Kṛṣṇa's dynasty, when Kṛṣṇa saw that they are becoming so powerful, that unnecessarily they are fighting, therefore to kill them, that fighting spirit was engaged for fighting amongst themselves, one another. Therefore they were all... Fighting, there is necessity; but if you misuse that fighting spirit...
Just like at the present moment the politicians, as soon as they see that they cannot manage things, in the country there is confusion, they declare some war so that the whole attention may be turned that side, and there will be no agitation of the internal dissatisfaction. This is diplomacy. This is diplomacy. We have seen it in Pakistan. As soon as they cannot rule over, they cannot, but they (indistinct), "Oh, the Hindus are our enemy. Kashmir, he has taken." Attention is diverted and they declare war, and again become defeated. So this kind of war is not required. This kind of war is not required. But war is there already, struggle for existence. Just like here, when Kṛṣṇa saw that the Yadu dynasty is becoming... On the strength of Kṛṣṇa, they have become so powerful that they (are) unnecessarily fighting, so Kṛṣṇa wanted that His family, may be..., it may not be degraded farther, so He wanted to kill them. And who can kill them? No outsider can kill them, they are Kṛṣṇa's descendants, that is not possible. Therefore yadūn yadubhir anyonyaṁ bhū-bhārān sañjahāra ha, they fighting amongst themselves, they reduced the burden of the world.
So it is... Kṛṣṇa is exhibiting how things are going on. As soon as there will be burdensome, there will be some war, pestilence, famine—and finished. And finished. You don't require to reduce population by contraceptive method. By nature's way, the wholesale it will be reduced, bhū-bhārān sañjahāra. By nature's way. Why should you commit sinful activities? You don't beget children unnecessarily and don't kill them. That is religion. That is civilization. Why should you unnecessarily produce children like cats and dog? Their śāstra says that don't become father, don't become mother if you cannot save your sons from death. This is the responsibility. This is father's, mother's, responsibility. Na mocayed yaḥ samupeta-mṛtyum, pitā na sa syāj jananī na sa syāt. One should not become, try to become father, one should not try to become mother if the parents cannot save the child from imminent death. That is the responsibility. And who is that father? Who is that mother? This is Vedic civilization. My Guru Mahārāja used to say that "I am a sannyāsī. I am not married, neither I am meant for marrying. But if I can produce Kṛṣṇa conscious children, I can marry hundred times." That is the responsibility. Don't produce cats and dogs; produce Kṛṣṇa devotees. Then you'll marry. Otherwise don't marry. This is Vedic injunction. Marriage is not meant for sense gratification. Marriage is meant for producing nice children, Kṛṣṇa devotees.
