Jalajā nava-lakṣāṇi. In the aquatics, there are 900,000 species of life. Now, if you have got your science, now go and see. This is Vedic knowledge. Perfect, without any doubt. Sthāvarā lakṣa-viṁśati. And the plants and trees, they are 2,000,000 species of life. So, ei rūpe brahmāṇḍa bhramite (CC Madhya 19.151). We are transmigrating from one species of life, one species of life, another, another, another, another... They cannot explain why there are so many varieties of life. The varieties of life is there because we have desire, kāma. "I want this." "All right, take this." Kṛṣṇa is immediately prepared. Ye yathā māṁ prapadyante (BG 4.11). "If you want, you can take it." But Kṛṣṇa says, ultimately, that "You'll never be happy in this way. Therefore you give up this business. Simply surrender unto Me." Sarva-dharmān parityajya mām ekaṁ śaraṇam (BG 18.66). So that is called akāma. So here it is said that akāmaḥ yajet puruṣaṁ param. If you want to be akāma, devoid of all material desires, then surrender to Kṛṣṇa.
That will save you from this business of rotating from one sort of body to another sort of body. Therefore Caitanya Mahāprabhu said, ei rūpe brahmāṇḍa bhramite kona bhāgyavān jīva (CC Madhya 19.151). To come to Kṛṣṇa consciousness is not very easy thing. It is by the grace of guru. Guru-kṛṣṇa. And grace of Kṛṣṇa. Combined together. One who sincerely wants to stop this business of repeated birth and death... But they do not understand that this is a suffering. They say, "Ah, let it happen." When they forget what is the suffering of birth. Birth, as I have many times explained... Nowadays, it is so much suffering that a child is born within the womb, and there is abortion, killed. "Kill him." But they do not understand the suffering, that one chance given that it will get a body and come out and maybe able to come to Kṛṣṇa consciousness, that opportunity... he's being killed within the womb. But these rascals, they do not know what is the suffering. Janma-mṛtyu-jarā-vyādhi (BG 13.9).
Kṛṣṇa says the sufferings of birth... They do not understand, such fools, that what is the suffering of birth. Even if you are not killed, you have to remain compact in a vat, airtight. And the worms, they are biting. So many things. Suffocated. That is one thing. But if he can live at least for ten months, the mother does not kill, abortion, then it has got a chance to come out. Otherwise, there is no chance to come out ever. He dies within the womb, again transferred to another womb, and again it is killed. So those who are too much sinful, those who are causing these abortions, they will get this sort of life. They will never see light. One womb, killed; another womb, killed; another womb, killed; another womb, killed. This is so sinful, this abortion. And the modern civilization and the priestly order, they are passing: "If the mother selects... otherwise, there is no objection, abortion." Such foolish world is going on. You see? There are so many subtle laws of nature.
