I have received your beads also, and I am returning them to you duly chanted. Now please increase your enthusiasm for pushing on this Krsna Consciousness movement and Krsna will inspire you with all intelligence for serving Him as much as you engage yourself with sincerity and devotion. Therefore to keep advancing in your spiritual power always be sure to chant at least the prescribed sixteen rounds of beads daily. This is the fundamental program for advancing more and more in Krsna Consciousness.
Letter to Giriraja, 7 April, 1970
