Hṛdayānanda: He asked about heart transplants, where does the soul go in heart transplant, when they change the heart from one body to another body. He's asking about that.
Prabhupāda: Heart changing?
Hanumān: No. Now they're doing this heart transplantation. They're taking the heart of one person...
Prabhupāda: The soul changes from this heart to that heart. That's all. Just like you are running your car. It stops. Then you change, this car to that car. That's all. (laughter) This is it. It is very common thing.
