Srila Prabhupada appeared to Prthuputra Swami, the first French sannyasi, just before Prthuputra died. Maharaja had done a lot of service for Srila Prabhupada’s preaching mission. But after Srila Prabhupada’s physical demise, Prthuputra left Krishna consciousness. He broke the regulative principle and went back to the sinful lifestyle he had led before. Nevertheless, he never criticized ISKCON or Krishna consciousness.
Some years later Prthuputra contracted AIDS. As the disease progressed, he ended up in hospital, and as it progressed further, he was hooked onto the machines which kept him alive. During his last, he was in coma.
As he was about to die, doctors gathered around his bed and tried to estimate how many days—if not hours—he had left. As they discussed his condition, all of a sudden Prthuputra opened his eyes, sat up in his bed, and looked towards the door. “Prabhupada, you came,” he said. Then he laid back on his bed, closed his eyes, and died.
Doctors later told this story to the devotees.
