The extra population, unnecessary. Varṇa-saṅkara. They are called varṇa-saṅkara. Varṇa-saṅkara . . . because by nature there must be brāhmaṇa, kṣatriya, vaiśya, śūdra, by nature. That should be organized. Head is head, tail is tail, not that head, tail, everything is one. That is called varṇa-saṅkara. Kṛṣṇa . . . Arjuna has argued that if the family members . . . if the woman becomes widow, then there will be varṇa-saṅkara population. Varṇa-saṅkara population means a population who cannot say who is his father. That is varṇa-saṅkara. Or who is caste does he belong, what is his father, what is his family. No, nothing, no information. That is called varṇa-saṅkara. So when the varṇa-saṅkara population increases, then the whole world becomes hell.
So in order to save the world to become hellish, the king was so alert. That is . . . that is also bhakti. Because the whole natural plan is to come back to home, back to Godhead. This is nature's plan. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). Just like the police department. What is the meaning of police department? Why government spends so much money for police department? Just to keep law and order. There must be. As soon as there is disobedience of law and order, immediately police department must go and punish and arrest. We can experience these things. Similarly, by God's side there is such department, police department. That is māyā, Durgādevī. Durgādevī, you have seen. Most of you might not have seen Durgādevī's picture, with trident, trident in the hand. The asura is being attacked by the trident. So this trident means threefold miseries. You have seen the picture, Mother . . . Goddess Durgā is piercing the trident just here on the heart. This trident means threefold miseries: adhyātmika, adhibhautika, adhidaivika. I have several times explained: pertaining to the body and mind, pertaining to the other living entities, adhibhautika; adhidaivika, pertaining to the nature's disturbance.
