Śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ [SB 1.2.17]. The whole world is full of sinful life. So we are creating the atmosphere, puṇya-śravaṇa. Chanting and hearing. Simply by these two processes. Puṇya-śravaṇa-kīrtanaḥ. Puṇya, pious. So anyone who is coming here, even he does not understand a single word which we are speaking, if he simply hears, he becomes pious. Simply by hearing. Even a child, he becomes pious. And unless we are free from our sinful life, we cannot understand about God.

yeṣāṁ tv anta-gataṁ pāpaṁ
janānāṁ puṇya-karmaṇām
te dvandva-moha-nirmuktā
bhajante māṁ dṛḍha-vratāḥ
[Bg. 7.28]

This is stated in the Bhagavad-gītā. So those who are sinful, they cannot understand what is God. Therefore the whole world is godless. They are so sinful, their life, their civilization, has been made so much sinful, the four principles of sinful: illicit sex, intoxication, meat-eating, and gambling. The whole world is full of these four business. Therefore they are all sinful. He may dress like a very nice gentleman, but he's a sinful man. So he cannot understand. Therefore it is very difficult to convince these rascals about God. They say, "I am, everyone is God, I am God, you are God, God is dead." They are so dull. You see? Therefore our business is to cleanse their heart.­­­­­­­­­­­­­­­­­
