All these boys and girls who are sitting here, you know that they have given up automatically. They have been able, by association with Kṛṣṇa. It has become very practical and easy thing to give up all these four principles of sinful activities. Because without being pure, you cannot understand the Supreme Pure. God is Supreme Pure. It is stated in the Bhagavad-gītā, yeṣām anta-gataṁ pāpaṁ janānāṁ puṇya-karmaṇām. Anyone who is completely free from the reaction of sinful life, yeṣām anta-gatam pāpaṁ janānāṁ puṇya-karmaṇām.
Now, how it is possible? If one is simply engaged in pious activities. The most pious activity is to be engaged in Kṛṣṇa consciousness movement. Pure. Then these are the different stages. Adau śraddhā tato sādhu-saṅgo tato bhajana-kriyā atha anartha-nivṛttiḥ syāt. Anartha means things we do not want. Artificially we are practiced to things. Just like meat-eating. Meat-eating, we do not practice it from the beginning of our birth.
Just after birth the child, the baby, requires little honey or little milk, not the meat. But afterwards, the parents or the guardians are teaching how to eat meat. This is not our human business. Human teeth is meant for eating fruits and grains. That is scientific. Our teeth is made in that.
So anyway, meat-eating, intoxication, illicit sex, as soon as one takes to Kṛṣṇa consciousness movement, these four pillars of sinful life is immediately broken.
