Gyan Daan Seva
Everything started by knowing new things. Srila Praphupada started educating people; he started making them powerful with knowledge about the scriptures. This knowledge has been contained in books which make for the oil on which the ISKCON machinery runs. It is only through genuine learning that one can touch the lives of people, give it perspective and draw them towards a higher purpose. Gyan Seva encompasses all of this. More than anything else, one becomes of the messenger of the Lord in spreading the spiritual message.
