The nine devotional process and how, by each process, one becomes perfect. Just like Pariksit Maharaja, simply hearing, and Sukadeva Gosvami, simply chanting, reciting Bhagavatam. So both of them got salvation. Laksmi, she is simply pada-sevanam, giving massage to the lotus feet of the Lord. Arjuna simply made friendship with Krsna. Hanuman simply worked as a hard servant.
He doesn’t know what He is… “Lord Ramacandra wants it.” Then it is done. Jump over. He does not know any philosophy. He has got bodily strength, so whatever Ramacandra says, he’ll do. He was asked to bring that medicine for Laksmana. He did not know where to find it: “Take this whole mountain.” [laughter] That is Hanuman. He was not intelligent. “Fight! We have to fight with Ravana. Then block his whole city by throwing stones and trees and dirt.” Everything became blocked; they could not move. So in one side he is born of animal life, he had no higher intelligence, but his staunch desire, that “I shall serve Lord Ramacandra…” By that. Only this desire made him perfect. Dasyam. Sravanam kirtanam visnoh [SB 7.5.23]. So smaranam. Prahlada Maharaja, five-years-old boy, how he could protest against such a powerful demon father? He was simply thinking of Krsna: “All right, my father is punishing me. What can I do?” Simply absorbed, smaranam.
