Allen Ginsberg: Now, what is Kalki's nature?
Prabhupāda: Kalki's nature, that is described in Bhāgavata. He will come just like a prince, royal dress with sword, and on horseback, simply killing, no preaching. All rascals killed. No more preaching. (laughing) That is the last. There will be no brain to understand what is God.
Allen Ginsberg: There will be no brain to understand God?
Prabhupāda: They will be so dull, so dull. It requires brain to understand. Just like in the Bhāgavata it is said that evaṁ prasanna-manaso (SB 1.2.20), "fully joyful," bhagavad-bhakti-yoga, "by practice of bhakti-yoga." Evaṁ prasanna-manaso bhagavad-bhakti-yogataḥ, mukta-saṅgasya: "and freed from all material contamination." He can understand God. Do you think God is so cheap thing, anyone will understand? Because they do not understand, they present something nonsense: "God is like this. God is like that. God is like that." And when God Himself comes, that "Here I am, Kṛṣṇa," they don't accept it. They'll create their own God.
