We must be purely chanting. But we should not be disappointed, even impure. Therefore we must have fixed chanting process. Because we are not in the pure stage. Therefore, by force, just like a boy in the school. We had this training in our childhood school. Our teacher would ask me, "You write ten pages, handwriting." So that means practicing ten pages, my handwriting will be set up. So if we do not even follow sixteen rounds, where is the question of chanting Hare Krsna? So don't be artificial; don't be a showbottle. Be real thing. And that is wanted. If you want real benefit of spiritual life, don't be showbottle. If one can chant purified offenseless, once krsna-nama, he is free from all material bondage. Once only.
