Jesuit: Is it by prayer to God that you help the world?
Prabhupāda: Yes, this is prayer: Hare Kṛṣṇa. Hare Kṛṣṇa means "O Kṛṣṇa, and Kṛṣṇa's energy, please accept me as Your servant."
Jesuit: But are you praying for all these people outside who do not belong to...
Prabhupāda: Oh, yes.
Jesuit: So you're...
Prabhupāda: Therefore we chant Hare Kṛṣṇa so that they can hear and take benefit. But they think that, "They are disturbing," but we are helping them.
Jesuit: And do you believe that God is pleased by your prayer and helps them because of your prayer?
Prabhupāda: That depends on God. God is fully independent. He may not like. You cannot force Him. But it is our duty to request Him. You cannot force Him. If He likes... if He does not like, that is His will, because He is the supreme will. But God likes. If a devotee requests Him something, He likes to accept. That is God's mercy. He takes the devotee's prayer very seriously. Therefore our another process is to take the shelter of a devotee first. Because even one is inferior, not to be accept by God, but if a devotee requests, "God, kindly accept this fellow," God accepts. Mercy of saintly... kṛpā-siddha. The Sanskrit word is kṛpā-siddha. He becomes perfect by the mercy of devotee.
