So brain may be a, a combination of nice matter, but it cannot work without the spirit soul. We should clearly understand this. And if we accept this body as the everything... Just like the other day, I told you, I met one big professor, Russian professor, in Moscow. He said, "Swamiji, after this body is finished, everything's finished." This is the atheistic theory. This is not new. In India there are many atheists, followers of Cārvāka. According to Cārvāka Muni, his theory is: bhasmi bhūtasya dehasya punaḥ kutaḥ punar āgamano bhavet ṛṇaṁ kṛtvā ghṛtaṁ pibet yāvad jīvet sukhaṁ jīvet. Ṛṇaṁ kṛtvā pibet. "Just live joyfully, merrily..." "No, I have no money." "All right. Take, beg, borrow and steal. Some way or other, get money." That is going on. "Get money some way or other and live." That is Cārvāka theory. Hedonism. "Get money..." So this is going, this civilization is going on. "Somehow or other, get money." Because without money, you cannot get woman, you cannot get nice palatable food, nice dress, nice apartment, nice car. "So bring money, somehow or other." Everyone is coming forward as very philanthropist leader. The aim is how to get money. That's all. That is their philanthropism. They, they speak so many nonsense things, but the real idea is how to get money.
So this is going on. At the present moment, they are after the sense gratification. They do not know that there is another life beyond sense gratification. They have no... That life is being taught in the Bhagavad-gītā, that "You are trying to advance your civilization for keeping this body fit, but you are not this body. Why you are wasting your time in that way?" Yasyātma-buddhiḥ kuṇape tri-dhātuke. Yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13). Anyone who is thinking that "I am this body," sva-dhīḥ kalatrādiṣu. And sva-dhīḥ means "My men, my own kinsmen." Who? "My children, my family, my society, my country," kalatrādiṣu. Sva-dhīḥ kalatrādiṣu bhauma ijya-dhīḥ: "And the land where these things have grown up, my body and my other relatives in relationship with this body, that is pūjya." Sva-dhīḥ kalatrādiṣu bhauma ijya... Nationalism: "My country. I shall die for this land. I shall sacrifice everything." Sva-dhīḥ kalatrādiṣu bhauma ijya-dhīḥ, yat-tīrtha-buddhiḥ salile. And those who are little advanced, pious, they go to places of pilgrimages, take a bath in the Ganges, and come out. They think that water is tīrtha. No. Tīrtha is saintly persons. Tīrtha-padam. You have to meet saintly persons to take lesson from them. Yat-tīrtha-buddhiḥ salile na karhicij janeṣu abhijñeṣu. You have to meet self-realized persons, those persons who do not care for these things. And in the bodily concept of life, they have been described in the śāstra: go-kharaḥ, "cow and asses."
