“If there is no need of guru,” Prabhupada said sharply, “why are they writing books to tell people? As soon as you tell someone something, that is guru.” When one visitor asked if some effort was required to obtain a guru, Prabhupada gave his confirmation. “Yes. Therefore Krishna says, tad viddhi pranipatena. Pranipat means you have to surrender. When you submit somewhere, you must test and then submit. That is sad-guru.”
“They say, sir,” Dr. Patel said, “that if you are very sincere then the sad-guru comes automatically to you … as you have come to us.”
Prabhupada answered, “Yes. Because Krishna is there. If He sees somebody is actually serious to understand Him… Therefore Dhruva Maharaja, he did not make any guru, but with fervent desire he went, ‘Yes, I shall find out Krishna.’ Mother said, ‘Krishna can be found in the forest.’ He went to the forest and began according to his own way. Then Krishna sent Narada Muni: ‘This boy is very serious; go and give him real mantra.’ That is Chaitanya Mahaprabhu, guru krsna krpaya paya bhakti lata bija. Two things required, guru and Krishna.“
