Krsna will arrange for everything. My Guru Maharaja used to say that “You do not try to preach for getting some money. Money will come automatically. On your feet money will say, ‘Please accept me.'” You should preach very sincerely. That is your business. Never bother that “Where is money? Where is money, money, money?”
