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.
Allen Ginsberg: So Kalki comes at the end of the Kali-yuga?
Prabhupāda: Yes.
Allen Ginsberg: And is Kalki connected with the Kali-yuga cycle?
Prabhupāda: Yes. Kalki, yes.
Allen Ginsberg: So He would come at the end of Kali-yuga to end the yuga.
Prabhupāda: Yes. Then Satya-yuga will begin.
Allen Ginsberg: Then what begins?
Prabhupāda: Satya-yuga.
Allen Ginsberg: Which is?
Prabhupāda: Satya-yuga, the pious. Satya-yuga. People will be pious, truthful, long-living.
