"One who takes asraya, shelter of a devotee, Krishna does not give him up. Krishna accepts him. Yasya prasadad bhagavat-prasadah... Because if that person who is giving shelter, if he's pleased, Krishna is immediately. If he recommends a fool, 'Oh, Krishna, here is a devotee,' Krishna will accept immediately. It doesn't matter whether he's a fool or rascal. Because he is recommended by representative, he will be accepted. Yasya pra... This is the meaning of yasya prasadad bhagavat-pra... Without his recommendation there is no entry in Krishna's kingdom.
"Yasya-prasadad na gatih kuto 'pi. If he displeases Krishna's representative, he has no entrance to the Krishna's kingdom, however learned he may be or whatever he may be. Immediately rejected."
(Srila Prabhupada conversation, December 12, 1970)
