"So a Kṛṣṇa conscious person should not be disturbed whether his preaching work is being accepted by the people or not. It doesn't matter. My Guru Mahārāja used to say that... If somebody said that 'We went to preach in such and such place. Only there were three or four, attendance.' So my Guru Mahārāja used to encourage them and it is factual—that 'Why, two, three men were there was sufficient. If there were none, you could speak and the walls would hear you.' You see. 'Why you are disappointed?' So even the walls, they hear, then our kīrtana is sufficient. You don't mind. Because only fortunate persons... Bahūnāṁ janmanām ante (BG 7.19). Manuṣyāṇāṁ sahasreṣu (BG 7.3). So to become God conscious, Kṛṣṇa conscious, is not very cheap thing. It requires a great amount of austerity, penance to come to this stage. So never be disappointed that because people are not responding. You see?
There are many good examples. When Lord Jesus Christ also preached God consciousness, only a few followers were there, and still, he had to sacrifice his life. But he was never disappointed. That should be attitude of the preacher. People may accept it or not accept it, we should go on. Because if Kṛṣṇa is satisfied, if Kṛṣṇa sees, 'Oh, these boys are doing very nice. They are trying their best to preach,' that is your reward. That's all. People may accept or not accept, it doesn't matter."
