Kirtanananda: How about if a disciple wants to use the help of Visnu for the spiritual master?
Prabhupada: Huh?
Kirtanananda: A disciple wants to take the aid of Visnu for serving the spiritual master.
Prabhupada: Hah. That is nice. That is for curing Visnu's representative. When we were in danger, there was so much obstruction for constructing the temple, and we prayed to Krsna that it should stopped. We prayed to Krsna, "Please give Your protection." That is for Visnu's purpose.
(break) ...Bhagavad-gita, arto 'rtharthi jijnasur (BG 7.16): when one is in distress, he comes to Krsna. So that is not pure bhakti. Pure bhakti means "I shall not take a farthing from Krsna; I shall give everything to Krsna." That is pure bhakti. "I shall not take any return from Visnu." Prahlada Maharaja says that "I am not a merchant, that for my service I take some return for it." No. But sometimes when, since we are not pure devotees, we have no other alternative than to beg Krsna for some material benefit. That is also good. They have said, catur-vidha bhajante mam sukrtinah, they're pious. Although they are not pure devotee, but they are pious. But the duskrtinah, they do not approach Him. That is the difference.
