How long will the Hare Krishna Movement last?

Allen Ginsberg - "Will people still be chanting Hare Krishna in 400,000 years?"

Srila Prabhupada - "No. Hare Krishna will be finished within ten thousand years (10,000 YEARS). There will be no more Hare Krishna".

Allen Ginsberg - "Ah. So what will be left?"

Srila Prabhupada - "Nothing. I'll kill you and eat you, and you shall kill me. You shall eat me. That will be left".

Allen Ginsberg - "After ten thousand years?"

Srila Prabhupada - "Yes, there will be no grain, no milk, no sugar, no fruit. So I will have to eat you, and you will have to eat me. Full facility for meat-eating.[Laughter.] Full facility. Krishna is very kind. He'll give you facility:

"All right. Why cows and calves? You take your own son. Yes. Eat nicely." Just like serpents, snakes -- they eat their own offspring. Also tigers. So this will happen. And there will be no brain to understand [God], no preachers, nothing. And then Krishna will come:

"All right, let Me kill you so that you will be saved."
