Visakha dasi: Prabhupada pointed out in his talks that even well-to-do people would come to get this prasadam. They didn't need it, they weren't in need of food, but they valued it as something spiritual, something that could help them in their spiritual life. And this Prabhupada said was the purpose of prasadam.
It's not just an altruistic activity that we give prasadam to poor people or destitute people. We can do that, but prasadam is for everyone because spiritually we are all poor, we are all destitute. We need this mercy from Krishna, and Prabhupada was very generous about it. The children would sometimes come twice or even thrice, and Prabhupada would smile and wag his finger at them; but he would give them again and again.
