And to become first-class man, the preliminary qualification is that you should not become sinful. So instead of becoming sinful, to become pious, you simply follow these four regulative principles. The first principle is illicit sex. That is forbidden. Sex is not forbidden, but illicit sex is forbidden. That is not very difficult. Everyone wants. That is the necessity of the body, that sex. As we want to eat, as we want to sleep, similarly, there is sex desire. But if you want to become first-class man, then don't have illicit sex. Except marriage, do not have sex. The human society... Therefore, human society, there is marriage. There is no marriage in the dog society. So therefore, sex life within marriage and regulative principle, that is not prohibited. That means anyone who follows these rules and regulation, he becomes purified and pious. Without becoming purified and pious, you cannot understand God. It is said therefore in the Bhagavad-gītā,
- yeṣāṁ tv anta-gataṁ pāpaṁ
- janānāṁ puṇya-karmaṇām
- te dvandva-moha-nirmuktā
- bhajante māṁ dṛḍha-vratāḥ
- (BG 7.28)
A person who is completely free from sinful activities, such person can become a devotee, a lover of God. So this Kṛṣṇa consciousness movement is teaching to the human society how to become purified. There is no such restriction that "This man can be purified; that man cannot be." No, there is nothing like that. Everyone can be purified if he desires to be so. So immediately we may not be able to purify. As it is prescribed—no illicit sex, no meat-eating, no gambling, no intoxication—it may not be possible because those who are accustomed, it is difficult to give up. Therefore the process is given very simple: "Chant Hare Kṛṣṇa." So purification is absolute. That is necessary. Without purification, you cannot understand God.
