In the vedas it says many times, that a part of every yagya is honoring brahmin priests through gifts (dakshina) of food, cloth and in this case a silver cup for the puja set. It is a way of honoring and preserving the vedic tradition, and besides all the priests have families and have to make a living! Of course in the "old day'' the gifts were cows and gold. but then again the yagyas were pretty much only for the wealthy.
We also donate clothes for the needy people. Anyone need help please contact us.
