Prabhupāda: That was Jagadish Chandra Bose's discovery. But the government will not give the credit to the Indians. Because Jagadish Chandra Bose happened to be Indian. These Britishers, they are so much envious. Therefore they will never admit that Bhagavad-gītā was spoken five thousand years ago. They'll bring all within the Christian period. That is their rascaldom.
Devotee: We went to a college and gave a class last week where the professor was saying that the Bhagavad-gītā is only two thousand years old, like that.
Prabhupāda: Yes. They will never accept this.
Yaśomatīnandana: One stupid guy was saying that there is some quotation in the Bhagavad-gītā from Book of John.
Prabhupāda: Huh?
Yaśomatīnandana: One stupid person, one man.
Prabhupāda: Oh, that is another rascaldom. Tava cārjuna (BG 4.5).
Svarūpa Dāmodara: Śrīla Prabhupāda, what about the heart transplant? The spirit soul is within the heart, but when the . . . in the medical science nowadays, the old heart can be replaced by a new one. So what happens with the spirit soul with the old one?
Prabhupāda: But that does not mean that new ones will increase their duration of life. That is our challenge.
Svarūpa Dāmodara: But the personality is changed?
Prabhupāda: No.
Svarūpa Dāmodara: Why not?
Prabhupāda: Why changed? Suppose if I sit from this chair to this chair. Why I am changed? I can change my seat. It does not mean that I am changed.
Karandhara: Change the heart also. The heart can change.
Prabhupāda: The heart is seat, sitting place.
Svarūpa Dāmodara: But the new heart had spirit soul from the new one.
Prabhupāda: Spirit soul, new or old there is. But if you can prove by changing the heart you can increase the duration of life, then you can catch the spirit soul.
Karandhara: That they're not able to do.
Prabhupāda: (chuckles) That is their nonsense.
Bali-mardana: None of them have lived very long.
Prabhupāda: No, they cannot be. Because by karmaṇā daiva-netreṇa (SB 3.31.1), by superior arrangement, karmaṇā, you have got this body. So you have to live within this body certain age. So if you change the body, new, that doesn't mean you prolong your life. That is not possible. It is the duration of life, that is considered. They are thinking by changing the heart they will increase the duration of life. That is not possible.
Svarūpa Dāmodara: So it is some sort of artificial transmigration?
Prabhupāda: Yes, like that. That transmigration taken . . . that is already explained in Bhagavad-gītā. Just like a baby becomes a child, child becomes boy, boy becomes youth, like that. Transmigration is going on continually. This is another type of transmigration. So it is a fact that by changing the heart the duration is not . . .?
Bali-mardana: No, most of them, they have lived a very short times. But still is it a fact that the soul is transplanted from one body to another body?
Prabhupāda: That can be done, yes. Sometimes yogīs, they can perform that better body, he transfers himself into that body. Just Śaṅkarācārya did. Yes.
Karandhara: What they do, though, they wait till someone's dying or dead, and immediately after they die, they take the heart. From somebody who had the weak heart they transplant, change the heart.
Prabhupāda: So what . . .? There is no benefit.
