So we should be callous with all these political, social… We should simply go on. That is Caitanya Mahaprabhu. He was callous. Family affairs, wife responsibility, for mother's responsibility, for… Nothing. Simply chant Hare Krsna. Kirtaniyah sada harih [Cc. Adi 17.31]. That is Caitanya Mahaprabhu's life. Even didn't care for anything, no responsibility. "My only business is chanting." That is…

So we have to study Caitanya Mahaprabhu's life. Except — this is the clear and simple truth — except chanting Hare Krsna mantra, there is no other business of the human being.

So this preaching is also chanting Hare Krsna mantra. This is preaching. That has been shown by all the disciples of Caitanya Mahaprabhu. All the Gosvamis, Haridasa Thakura and others only did this: how to develop Krsna consciousness, no other business. That is sannyasa. He has no other business. To preach Krsna consciousness, to practice Krsna consciousness, to convince Krsna consciousness, that's all. No other business.

We don't take part in politics, sociology and mental speculation, science, or so on, so on — all nonsense. We reject all; kicked out. That is the perfection. It is simply waste of time. These are all superficial. Just like waves in the sea.
