Tamal Krishna: Prabhupada wrote me in a letter, “Throughout my life, I had so many opportunities for sense gratification, but Krishna always saved me. I never knew what is meat-eating, gambling, intoxication or illicit sex.” He wrote, “There was never a moment when I was ever forgetful of Krishna.” He actually wrote that in a letter to me. He said, “There was never a moment when I was ever forgetful of Krishna.“
