So this how to become immortal, there is process recommended in the śāstras. That is in India. That is nowhere else. If you actually serious about becoming immortal, then you should study the Vedic literatures from India. That is Caitanya Mahāprabhu's mission, that in India there is the process, how to become immortal. So He recommended, therefore, He desired, that Indians, you Indians, you have got the facility. Don't spoil your life by imitating the so-called rascal scientists of the Western countries, but you take advantage of the science, spiritual science, which is in India, and distribute the knowledge, because they are in ignorance. Therefore He says,
- bhārata bhūmite manuṣya janma haila yāra
- janma sārthaka kari' karo paropakāra
- (CC Adi 9.41)
This should be the India's business. This whole world is in darkness, demonic civilization. And India, there is the remedy. So if the Indians take advantage and make his life perfect and then go to the Western countries and distribute this immortal knowledge, that is real business of India. Unfortunately, they are trying to imitate. There is no thing, nothing to imitate. And if you say that they have discovered so many material comforts, that is all right. But with all your material comforts, you cannot become immortal. That is certain. That is certain. But you are desiring how to become immortal. That science is in India. That is tapasya. Tapasya means brahmacaryena. Tapasā brahmacaryeṇa yamena niyamena vā tyāgena śrota-śaucābhyām. . . (SB 6.1.13). This, this is the śāstra.
So if you want to learn that science, how to become immortal, then you have to undergo austerities. That austerities begins with brahmācārya. Tapasā brahmacaryeṇa. Brahmacarya means controlling sex life. That is required. If you can control sex impulse. . . Because that is the medium of bondage. Here in this material world everyone is working hard to enjoy sex life. That is the main aim. Main aim is. . . And that you will find, in your country especially, very, very prominent. In Paris very, very old men, they are going to the club at night simply for the same purpose. So this has to be controlled. Controlled means mind and the senses. And the prominent sense is sex. That is called control.
