Caitanya Mahaprabhu’s movement is so nice that you don’t require to acquire something artificial. No. Wherever you are, remain there. Simply hear. And preaching means to propagate or to vibrate what Krsna has said. So this is the position of the preacher, that you simply repeat, like a parrot, no qualification. You simply … Whatever is said in the Bhagavad-gita, you repeat. And the others simply hear. Sravanam kirtanam [SB 7.5.23]. Then both of them become liberated.

There is no question of that, to become a qualified person. This is the only qualification, that a preacher should preach only what Krsna has said. That’s all. No manufacturing, no concoction. And the audience? They will hear from such person who does not speak anything else except Krsna’s teaching, that’s all. These two things, if carried, then your both the life,(?) the sravanam kirtanam, the one who is speaking and one who is hearing, both of them are benefited.
