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 (SB 6.1.13). 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. So if you want to become immortal, then you must practice this. Of course, in Western countries, it is very difficult. They say, "It is impossible." Big, big men, they say, "It is impossible." Yes, it is impossible. Therefore śāstra has given concession that you require sex life, but enjoy it in married life, but no illicit sex. At least, stop this. If you want to be immortal, these things are to be followed: no illicit sex, no intoxication, no meat-eating, no gambling. Then you can think of immortality, gradually. That is called tapasya. Tapasā brahmacaryeṇa (SB 6.1.13). Every śāstra, you'll find. At least at the end of life one should be completely free from these bad habits. That is called sannyāsa. Don't cheat, accept sannyāsa and indulge in these things. Don't be cheater. That is very bad. Sannyāsa means to take vow. In other station of life, there may be we fall down. But sannyāsa means no, no falldown. Therefore we have now taken very seriously. Unless one is found completely competent to accept sannyāsa, there is no more use of awarding sannyāsa. So this is the process. Tapasā brahmacaryeṇa (SB 6.1.13). Brahmacarya is very, very essential. And that is, when one becomes detestful to sex life, that is the beginning of spiritual life. That is the beginning of spiritual life.
So immortality is not very difficult thing. Simply one has to adopt the method, process, as recommended in the śāstra, and then you can become immortal. Kṛṣṇa says, janma karma ca me divyaṁ yo jānāti tattvataḥ, tyaktā dehaṁ punar janma naiti... (BG 4.9). Punar janma naiti—this is immortality. The Kṛṣṇa says, punar janma na. "No more punar janma." And if you have no punar janma, there is no punar death, punar vyadhaka, or punar disease. Punar means again. So if you can stop your punar janma—no more taking birth—that is perfection of life. Therefore it is recommended that the guardians, namely the guru, spiritual master, the father, the mother, the king, or the government. The whole system should be so centralized that people may be saved from this process of punar janma. That is real government, real parenthood, real guruism—how to save the disciples or the citizens or the son, subordinates. They come to your shelter. Just like these children have come to the shelter of father and mother, the disciples have come to the shelter of guru. The citizens are expecting good government. So they are subordinate, expecting protection from the superior. Therefore the whole scheme should be how to protect them from repetition of death. Na mocayed yaḥ samupeta-mṛtyum. We are entangled by this process of birth, death, old age and disease, and it is the duty of the guru, duty of the father, duty of the mother, duty of the government, how to save them from this process of birth, death, old and di... That is civilization. Otherwise it is dog civilization. What is the meaning? This is civilization.
So whole Vedic system is designed in such a way that ultimately one is saved from this process of birth, death, old age and disease. Long, long ago, when Viśvāmitra Muni came to Mahārāja Daśaratha for begging Rāma-Lakṣmaṇa to take them to the forest because one demon was disturbing... They could kill, but the killing business is for the kṣatriyas. This is Vedic civilization. It is not the business of the brāhmaṇa. So the first reception Viśvāmitra Muni got from Mahārāja Daśaratha, that aihiṣṭhaṁ yat punar-janma-jayāya: "You are... You great sages, saintly persons, you have given up the society. You are living alone in the forest. What is the purpose? The purpose is punar-janma-jayāya, to conquer over repetition of birth." This is the purpose. Similarly, our, this Kṛṣṇa consciousness movement is also meant for the same purpose, punar-janma-jayāya, for conquering over repetition of birth and death. You should always remember this. A little mistake will spoil the whole scheme, little mistake. Nature is very strong. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). Very, very strong. So you all, boys and girls, those who have come from America, I am very much thankful to you. But don't be less serious. Be very serious. And another thing I'll request especially to the Americans, that America has got good potentiality to save the world, so if you preach very nicely in your country... And not all of them will be interested, but if a section of men in your country, you can turn them to become Kṛṣṇa conscious, it will be great benefit to the whole world. But the aim is the same, punar-janma-jayāya: to gain victory over this process of birth, death and old age. This is not fiction; this is fact. People are not serious. But you can teach your people; otherwise, the whole human society is at risk. They are like animals, without any... Especially this communist movement is very, very dangerous—to make a big animals. They are already animals, and this movement is making big animals.
So I am speaking to America because America is a little serious against this communistic movement. And it can be counteracted because the process is current since a very, very long time. Deva asura, devāsura, the fight between the demigods and the demons. So the same fight is there in different name, "Communists and the capitalists." But the capitalists are also eighty percent, ninety percent demons. Yes. Because they do not know the science of God. That is demonic principle. So there is good chance in your country to make them, or they rectify their demonic principles. And then they will be very, (I) mean, strongly able to fight with the other demons. Because if we become deva... Deva means Vaiṣṇava. Viṣṇu-bhakto bhaved deva āsuras tad-viparyayaḥ. Those who are devotees of Lord Viṣṇu, they are called devaḥ, or demigods. And those who are just the opposite number... The opposite number, also, they have got some god. Just like the demons, they worship especially Lord Śiva. Or Rāvaṇa, the example... We are not accusing unnecessarily. Rāvaṇa was a great demon, but he was devotee... Worshiping Lord Śiva means to gain some material profit. And in the worshiping Viṣṇu there is material profit. That is given by Viṣṇu. That is not karma. But Vaiṣṇava, they are not aspiring after any material profit. The material profit automatically comes. But they, they do not desire. Anyābhilāṣitā-śūnyam (Brs. 1.1.11). Material profit is not their aim of life. Their aim of life—how to satisfy Viṣṇu, Lord Viṣṇu. That is Vaiṣṇava. Viṣṇur asya devataḥ. Na te... And the demons, they do not know that to become Vaiṣṇava, that is the highest perfection of life. They do not know it.
