Srila Prabhupada asked this question: what will it take for this movement to go on?
He asked it to his leading men. They were afraid because the question was asked with a lot of intensity, so it was quiet for a while.
Finally, one said, “Sincerity.”
Srila Prabhupada said, “No, that’s not enough!”
Everyone was , well, saying, sincerity is not enough? Then what else?
Prabhupada said, “Intelligence!. It takes intelligence for this movement to go on.”
So this is what we are looking at – sincerity and intelligence!
