Svarūpa Dāmodara: But a scientist will say that, "I can show you what the aroma looks like."
Prabhupāda: They cannot show you. That is another stupidity . . . (indistinct) . . . anything practically. Now here is . . . who can deny that Kṛṣṇa says that avināśi tu tad viddhi yena sar . . . there is a thing within the body which is eternal? And what is that thing which is spreading consciousness? And you show what is that thing which is spreading consciousness. Then I shall accept you as scientist.
Karandhara: They would say: "How can we believe Kṛṣṇa?"
Prabhupāda: No, no, you don't believe. That here is a fact, that there is something within the body which is spreading consciousness. That is eternal. There is no question of believing. It is a fact. Now you show what is that fact, where is that fact.
Svarūpa Dāmodara: They'll say it's just biochemical reactions.
Prabhupāda: Biochemical . . . you simply do it, rascal. You cannot do it. (Hṛdayānanda laughs) You rascal simply speak, but you cannot do it. That is our contention.
Hṛdayānanda: Jaya.
Prabhupāda: Therefore you are rascal. You speak something which is beyond your power.
Yaśomatīnandana: Prabhupāda, it solves . . .
Prabhupāda: Yes. Therefore it is simply cheating people. And we, Kṛṣṇa conscious men, we want to stop this cheating, any way . . .
Karandhara: They'd say we also cannot prove the soul is eternal.
Prabhupāda: No, there is proof. There is something. We accept it, but you don't accept it. There are so many things. There are so many things you do not see, but still you accept it. Just like without father there cannot be son. Now you have not seen your father, but mother says: "Here is your father." You have to believe it. It is a fact.
