And now it is practical. Now we are... According to śāstra, we have prescribed, "No illicit sex, no meat-eating, no gambling, no intoxication." Four no's. Then you become free from sinful activities. And then chant Hare Kṛṣṇa. Your life is successful. It is not very difficult, provided you are serious to take it. So that is our request. Harer nāma harer nāma harer nāmaiva kevalam (CC Adi 17.21). Even if you cannot give up the four principles of sinful life immediately, but you take to Kṛṣṇa consciousness. Chant Hare Kṛṣṇa mantra. Then you gradually get strength.
Just like these European, American boys. From their childhood they are trained up for this sinful life but they have given up completely. Young men. Still, they have given up. So the method is very simple. Ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpaṇam (CC Antya 20.12). If we chant Hare Kṛṣṇa mantra, then the mirror of the core of heart will be cleansed. Ceto-darpaṇa-mārjanam. And then bhava-mahā-dāvāgni-nirvāpaṇam.
