Hari Sauri: There was an emotional reunion this afternoon between Srila Prabhupada and Hayagriva Prabhu. Although he was one of Srila Prabhupada's first disciples, he has been away from devotional service for some years. He has come now to finish the philosophy book project and to be with Prabhupada for some time. He walked slowly into Prabhupada's room, his face flushed and his deep voice trembling. "It's your old Hayagriva, Prabhupada," he choked out, and fell sobbing to the floor in full length dandavats. Prabhupada sat behind his desk, silent, but clearly moved by the sight of his sometimes - wayward son.
When Hayagriva got up Prabhupada gave him a garland, and remarked to Radhaballabha Dasa and me how Hayagriva had been sent by Krishna to help him spread Krishna consciousness all over the world. In reply, Hayagriva said that he had never forgotten Prabhupada, not even for a day. Prabhupada was deeply affected by this and said that he also had never forgotten Hayagriva. "I was thinking, has Hayagriva gone away? I was thinking like that." His voice broke and he was unable to speak for a few seconds. Although he tried to check his tears, still some trickled from the corners of his eyes. Then he tipped his head from side to side. "All right," he said, and we all left.
Prabhupada has so much affection for his disciples - no one can estimate how much. It was very apparent that he never forgets any devotional service that has been rendered to him.
