Prabhupāda: Yes. Avināśi tu tad viddhi yena sarvam idaṁ tatam. At the present moment, because your these blunt eyes cannot see the soul, you have to learn it by appreciation. Anuvarga. It is called anuvarga, appreciation. Just like Kṛṣṇa says that tad viddhi, that, that thing which is spreading consciousness, that is soul. Now you can perceive there must be something which is now absent; otherwise why there is no consciousness? Where is the difficulty? If you do not see, you can understand it. Just like the same example, when good aroma is carried. So somebody says: "This good aroma is coming because the air is passing through a flower garden, therefore this aroma." Now this is a fact, but you cannot see the aroma or the air. But you hear from an experienced man. That is the way of understanding which is beyond your sense perception.
But these rascals, simply they are depending on their blunt senses, these stupids, so-called scientist. Therefore they're stupid. They simply believe on their eyes. They do not know how much defective these eyes and senses are. Incomplete. That they do not know. They believe on their defective senses. Akṣaja. Akṣaja, akṣa. Experiment. Everything experimented. Vedas says don't try to explain which is beyond your sense. How you will explain? It is not possible. Acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet (Mahābhārata, Bhīṣma parva 5.22). It is acintya; it is beyond your conception. Why you are wasting your time?
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.
Karandhara: But they can experience being a father themselves.
Prabhupāda: Ah? Ah?
Karandhara: They can experience that, 'cause they can be a father themselves.
Prabhupāda: They can be father themselves?
Karandhara: Yes.
Prabhupāda: What is that? Without son how one becomes father?
Karandhara: No, but they . . . that example falls within the range of their experience, because they can also be a father.
Prabhupāda: No, not to your experience. But a superior experience, say mother.
Hṛdayānanda: Yes.
Prabhupāda: Not your experience. You cannot say by experience who is your father. Your mother can say.
Karandhara: No, but the example that I have a father can be appreciated because I can also be a father.
Prabhupāda: But therefore if that appreciation is there, that avināśi tu tad viddhi yena . . . the consciousness is spreading from the soul, so you have to appreciate there must be something from which consciousness comes. That you cannot deny.
