Śyāmasundara: In order for that statement or that proposition to be true, there must be evidence.
Prabhupāda: This is evidence: that there is no soul. The self, the individual soul, is now departed; therefore this body is lump of matter. This is evidence. And because the soul is there, therefore the body changes or develops. Just like if a child is born dead, then the body does not develop or changes. It remains in the same condition. But so long the soul is there, the child grows or changes his body. That is evidence. Because the soul is there, therefore the child is growing or changing body from childhood to boyhood, boyhood to youth. Suppose a child is born, doctor says it is dead child. You say something is wanted, but what is that something? You do not know. Otherwise, if you know, you add it. What is that something? Suggest, what is that something? Simply vague idea something, that is nonsense idea. That is not science. You must give, "This is wanting." Suppose that you say that the blood, the redness, just like nowadays blood supply is the theory, so what is this blood? Blood is a liquid, red liquid, like chemical or something, with some salt. So you can add salt, just like in cholera cases, they add saline injection. So dead body, you give saline injection, make it red by some color, give him life. If you say that "Red blood is now white," so make it red. What is the difficulty? There is no difficulty. There are so many chemicals. If you say the redness is the life, then there are many natural products, just like jewels, by nature it is red. Why is it not alive? Why it is not alive? By natural redness of something, if you say that is the cause of life, then there are many jewels. What is called, jewels?
Śyāmasundara: Ruby.
Prabhupāda: Ruby. Why it is not alive? Redness is there. Therefore we have to accept your identification with the soul, not with this body; otherwise this is nonsense.
Śyāmasundara: He is not disputing that there is soul or there is not soul. He is merely putting forward a principle to test something, if it is true or false.
Prabhupāda: This is the test. This is the test. Because the soul is there, therefore the body is moving.
