Those who are simply engaged in sinful activities, they cannot appreciate this Krsna consciousness movement. That is not possible. But it is a chance given to everyone. We are flattering, "Please come here. Please..." This is our business on behalf of Krsna. As Krsna comes personally to teach Bhagavad-gita and ask everyone, sarva-dharman parityajya mam ekam saranam vraja [BG 18.66], our business is that.
