Don't think that at home you will be perfect. That is not possible. At home there is no such facilities. Here you will get the facilities. Here the devotees, they are actually following the instruction of mad-asrayah, one who has taken the shelter. They are rising early in the morning. And at home you will think, "Oh, what is early in the morning?" [laughter] "Let me enjoy sleep."
So there is no such facilities at home. Therefore this institution is started. If you are serious about Krsna consciousness, if you are serious about increasing your attachment for Krsna, then you should come and live with the devotees.
