Srila Prabhupada did not start preaching immediately in his life either. Rather, he underwent many difficulties in his business, and he often said that it took him years to fulfill his spiritual master’s order that he preach in the English language. Still, he was always preparing to perform this service, and meditation on his guru’s order became his daily meditation and thus part of his sadhana. Srila Prabhupäda was nitya-siddha, a devotee who came from the spiritual world to teach by his own example how to give up household life and dedicate one’s life fully to the Lord’s service. Sometimes the nitya-siddhas descend to teach many things—how to live as surrendered householders among them.
