"So this transcendental sound, Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare, you don't think that I have come here -- it is my personal manufacture. No. It is not. No. It is not my personal manufacture. It is authorized just like the post box is authorized, because all previous acaryas, all previous authorized persons in this line, they have done it. Just like see Caitanya Mahaprabhu. He is chanting and dancing, chanting and dancing, you see, the same thing. This picture is before you so that gradually, when you feel ecstasy, you will also dance like Him. And when you automatically dance, then you will know that the thing is already realized. Not artificially, but when you feel, 'Oh, let me dance. It is so much ecstatic. Let me dance.' Nothing should be done artificially. Let everything come automatically. And only we have to follow. Mahajano yena gatah sa panthah (Cc. Madhya 17.186)."
