Madhavananda: From the very beginning, I always loved kirtan and once in Calcutta after I had lead a kirtan in front of the Deities, Prabhupada’s servant came and said, “Prabhupada wants to see you.” I went and Srila Prabhupada said, “That was a very nice kirtan.” I said, “Oh, thank you.” And he said, “But it is not GA-dad-hara, it is Ga-DAD-hara.” So sometimes even today I cringe when I hear devotees saying GA-dad-hara, sri-krsna-caitanya prabhu nityananda, sri-advaita gadadhara srivasadi-gaura-bhakta-vrnda, and I remember Prabhupada saying that to me. But I was moved by Srila Prabhupada’s generous compliment.
