Kirtanananda das: Along towards summer Prabhupada went to Montreal, and I wrote to him and begged forgiveness for my offenses and told him I couldn’t forget him and couldn’t forget Krishna consciousness and I wanted to surrender to him. He wrote back and said, “Oh, my dear son, how have I ever lost you? I have been crying to Krishna, ‘How have I lost Kirtanananda?’” And he invited us to come and visit him in Montreal. We did, and he embraced me very warmly and said, “Now it is confirmed that we cannot be separated.”
