There are so many talks about to keep the varṇāśrama intact for peaceful condition of the society, and the modern problem, the overpopulation. We . . . in the śāstras, in the Vedic literature, we don't find such thing as overpopulation, because the living entities are already fixed up. From the Padma Purāṇa, we can understand that the living entities, they're very, very small particles of the supreme spirit soul, or God. Mamaivāṁśo jīva-bhūtaḥ (BG 15.7). And their dimension is also mentioned, keśāgra-śata-bhāgasya śatadhā kalpitasya ca (Śvetāśvatara Upaniṣad 5.9): the one ten-thousandth part of the top of the hair. And jīva-bhāgo sa vijñeya sa anantaya kalpate. So the living entities are already ananta, unlimited. In another place of Upaniṣad, Kaṭhopaniṣad, we find that nityo nityānāṁ cetanaś cetanānām eko yo bahūnāṁ vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13). These living entities, they are maintained. Their provision for their maintenance is already there, made by God. So there is no question of overpopulation. The question is varṇa-saṅkara. Varṇa-saṅkara, that is the problem.
So the human life is meant for systematic organization of spiritual realization. That is human life. There is evolutionary process from low-grade life, from aquatics to trees, plants, from trees, plants, to insect, from insect to birds, and then from birds to the beast, from beast to human being. So there are 8,400,000's of living entities in different species of life. And in the Bhagavad-gītā it is said:
- sarva-yoniṣu kaunteya
- sambhavanti mūrtayo yāḥ
- tāsāṁ mahad-yonir brahma
- ahaṁ bīja-pradaḥ pitā
- (BG 14.4)
