"If they do not like the noise of our kirtana there, we shall make it more noisy. They shall get out, not us. So go on performing Hari kirtana. Simply by the noise of kirtana demons go away."

"Live as simply as possible without any exaggeration, regularly hold Krishna Kirtana, and try to convince people about the non-sectarian nature of Krishna Consciousness। That will make you successful."
