Devotee: Srila Prabhupada, sometimes when we go preaching, people do not want to take Krsna consciousness. Sometimes they actually…

Prabhupada: So if they want to take, then where is the question of preaching? Because they do not want to take, you have to preach. Otherwise, where is the necessity of preaching? [laughter] You have to prepare yourself in such a way that nobody is dying for your Krsna consciousness, but you have to convince him that “Your life is spoiled without Krsna consciousness.” That is your capacity. They are under the clutches of maya.
