Amogha Dasa: I felt that I had been very unworthy of Srila Prabhupada. I had so much difficulty keeping regulated and not eating too much. I didn’t type very well. Like that, I was feeling that I am not very good. In this mood, I put my hands up and silently said prayers and obeisances to Srila Prabhupada.
Just after that Srila Prabhupada, turned and said, “Just by offering obeisances all good activity is performed.”
