Madhavananda das: I was in Srila Prabhupada's room with him in Calcutta. I was the temple president there, so I got access to Srila Prabhupada. So I went in and one day I was just there with him alone, and for some reason I asked this question. I don't know why, but I did. I said, "Srila Prabhupada, when you leave us, who will succeed you?" And he said, "That will be revealed to you." Then he looked at me and he said, "You will become guru." Then he said, "I want all of my disciples to become guru."
And then he said, "Yare dekha, tare kaha, Krishna'-upadesa, amara ajnaya guru hana tara ei desa," which is the verse that Lord Chaitanya Mahaprabhu spoke to the South Indian brahmana. I think it was Venkata Bhatta. When he left South India and he was lamenting, "What am I to do?" And Lord Chaitanya said, "Whoever you see, tell them about Krishna. Whoever you speak to, tell them about the instructions of Krishna given in the Srimad-Bhagavatam and the Bhagavad-gita. And on My order, you deliver this land." So Prabhupada quoted that verse and he said, "This is how this Krishna consciousness movement will be spread."
