Śrīmad-Bhāgavatam 7.9.35
—
Māyāpur, March 13, 1976
So those who are ordinarily sinful, they can at least see the light once, but those who are very severely sinful, they're killed within the womb. They cannot see even the light coming out. There are so many cases now, it is very (indistinct) that so many children, before coming out of the womb of the mother and before seeing the light of the sun, they are killed. And after killing, after being killed, the body is finished. Then he has to be put another body. Then enters another mother's body. Again the body is developed, and again he is killed. Just imagine. This... Because if... Tit for tat. If I kill a child in the womb—"Now I am very much proud of my scientific advancement"—then I am have to be killed in my birth. That's all.
You cannot avoid this nature's law. Daivī hy eṣā guṇamayī mama māyā duratyayā [Bg. 7.14]. There is very, very sūkṣma. The word is used sūkṣma, very, very fine laws. Who can see it? Ātma-yoni, so he's also not free. Although he is Lord Brahmā, he's also not free. He's perplexed: "Wherefrom I came? What is the source of my birth in darkness?" He could see only the lotus flower on which he was sitting, nothing else. Exactly our position... Just like so many scientists, they think that this world is everything, and other planets and worlds, there is no life. Only because he is there, there is life. This is the modern presentation.
