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.
Devotee or Guest: (Spanish)
Hṛdayānanda: If by purifying ourselves we feel our relationship that we have with the Supreme Personality of Godhead?
Prabhupāda: Yes, that is the center of purification.
Hanumān: Prabhupāda, I would like to know, if there is no birth in the spiritual world, how do we re-enter the spiritual world?
Prabhupāda: Hm? Birth means, first of all you take your birth where Kṛṣṇa is now present. Kṛṣṇa is present in one of the universes. There are innumerable universes. So you take your birth in the next universe, or where Kṛṣṇa is now. Then you become trained up. And when you are trained up, then you personally go to Vaikuṇṭha. No birth.
