Svarūpa Dāmodara: Because I'm conscious.
Prabhupāda: Yes. Therefore your consciousness is being revived. Come to the standard of Kṛṣṇa consciousness, you'll be happy. That is our business. His consciousness is being misled by so many ways. Therefore we are trying to give him the standard consciousness, "Come to this point, you'll be happy."
Svarūpa Dāmodara: How to prove that the soul is eternal?
Prabhupāda: That is the first lesson. You do not understand? You are a child, now you're a grown up boy. Where is your childhood? Where is that body? Ha? The dead body does not exist but you are existing. That means you're eternal. Body has changed, but you have not changed. Circumstances have changed, but you have not changed. This is the proof of (indistinct). What do you want more? You may remember that I did yesterday these things, today I remember yesterday's activities, but your body of yesterday is not this body. Do you admit or not? As a scientist, the body has changed already. He cannot say that 1973, twelfth May yesterday. He cannot say. It is already changed. But you remember everything of yesterday. That is eternity. The body has changed, but you remember everything. Therefore you are eternal, body's not eternal. This is the proof. Simple proof, even a child can understand. But they'll not understand. That is the difficulty.
Svarūpa Dāmodara: They want some more.
Prabhupāda: What is that more? It is a simple fact. Just like yesterday, day before yesterday, day before that we saw that stool. We therefore criticize. You are seeing for the last three days the stool, it is not cleansed. But day before yesterday's body, yesterday's body is not this body. And my body has changed, but I remember. Therefore I'm eternal. This is the proof. Eternity means I'm so... my body's changing, but I'm not changing. Just like, I'm old man. I sometimes think, "Oh, I was jumping like this and now I cannot jump." So my body has changed. But I want to jump. But I cannot do it. So that jumping propensity is my eternal propensity. But due to this body, I cannot do it. This is (indistinct).
Karandhara: They would say that, according to their observations, that nature of eternity only lasts one body.
Prabhupāda: That is their foolishness because, as this body... That is explained in the Bhagavad-gītā: tathā dehāntara-prāptiḥ (BG 2.13). As this body's changing in my experience, similarly, there's another change.
Karandhara: Well, actually, they're able to observe this change, but they can't observe that change.
Prabhupāda: But you cannot observe, your rascal eyes are so imperfect, you cannot observe so many things. That does not mean science. Why don't you admit your imperfectional senses? You first of all admit the imperfectional senses. You cannot see. You cannot experience. That, does it mean that is science? So many dogs they cannot understand what is the law of nature. Does it mean that nature does not exist? Why do you think your sense are perfect? First of all, admit that you're the most imperfect.
Karandhara: They'll admit that, but they say the way of becoming perfect is through objective information and experience.
Prabhupāda: No. Way of becoming perfect is different. You cannot become perfect by your imperfect thinking. How you can become perfect?
