We are so ignorant of this law of karma, we are thinking, "Now this position of American or Indian or this or that, for fifty years or sixty years, utmost—that is one, everything, all in all. There is no more life." Yes. I have talked with many big, big professors. They are under the impression: atheism, voidism, that after death there is nothing; everything is void, finished. Atheism. Bhasmi-bhūtasya dehasya kunaḥ . . . kutaḥ punar āgamanaṁ bhavet (Cārvāka Muni): "The body is burned into ashes. Who is coming again?" This is atheism. Because the atheist, they cannot see that how the soul is transmigrated by the subtle body from one body to another. They have no . . . gross. Gross materialists. So we should not follow the gross materialists, but we should follow the perfect leader, Kṛṣṇa, who says, tathā dehāntara-prāptir dhīras tatra na muhyati (BG 2.13). This we must follow. That is human civilization.
Therefore he prescribes that brāhmaṇa, kṣatriya, vaiśya, śūdra. Either you become brāhmaṇa or follow the instruction of the brāhmaṇas, then your life is perfect. Both things are there. If you like to be brāhmaṇa, that you can become also. Māṁ hi pārtha vyapāśritya (BG 9.32). This is Kṛṣṇa consciousness movement. Because in this age everyone is a śūdra, kalau śūdra-sambhavaḥ . . . there is no culture. There is no brahminical culture, kṣatriya culture. Therefore all together, they are simply śūdras. So this Kṛṣṇa consciousness movement is to raise the śūdras or less than that.
