There are many things which keep me going, one of which is the association of my godbrothers. There are many godbrothers of mine in this movement who really inspire me by their dedication to Srila Prabhupada's mission, their taste for chanting and hearing, the depth of their wisdom, and their wonderful devotional qualities. So, as you mentioned, Srila Prabhupada certainly is the fountainhead of our inspiration, and is the primary source of my inspiration as well. But to be honest, I see Srila Prabhupada in my godbrothers too. Actually, if I am really to be honest, I also see Srila Prabhupada in some of my godnephews and nieces. I know of some very dedicated devotees, with whom I am serving, and although they are not Srila Prabhupada's direct disciples, their commitment in serving his mission binds me into a loving commitment to assist them.
