Prabhupāda: That is the way of Vedic understanding. Vedic understanding means you have to accept whatever is stated in the Vedas without any argument.
Prof. Kotovsky: So forget about Vedas. Our approach is we don't believe in anything without argument. We can believe only on anything based on argument.
Prabhupāda: Yes, that...
Prof. Kotovsky: Here is the basic...
Prabhupāda: No, no, that is allowed.
Prof. Kotovsky: ...projecting (?).
Prabhupāda: That is allowed. That is stated in the Bhagavad-gītā, tad viddhi praṇipātena paripraśnena (BG 4.34), paripraśnena sevayā.Paripraṣna, argument, is allowed, but not with a challenging spirit. With a spirit to rightly understand. Praṇipātena paripraśnena. That... Argument is not denied. But so far Vedic statements are there, they are infallible, infallible, and the followers of the Vedas, they accept in that way. For example, just like cow dung.
Prof. Kotovsky: Yes.
Prabhupāda: It is the stool of an animal. Now, the Vedic statement there is: "As soon as you touch the stool of any animal, you are impure. You have to purify yourself by taking bath." Even in your own stool... According to Hindu system, if you go to evacuate, after coming you have to take bath.
Prof. Kotovsky: This is quite intact with modern medicine knowledge...
Prabhupāda: Yes.
Guest: ...that you must clean yourself.
Prabhupāda: Now...
Prof. Kotovsky: Yes, that's right.
Prabhupāda: But another place it is stated that "Cow dung, although it is the stool of an animal, it is pure." Even if you apply in an impure place, you become purified. Now, this is superficially contradicting. In one place it is said that "The stool of an animal is impure. As soon as you touch, you have to be purified," and another place it is said that "Cow dung is pure." So according to our knowledge, it is contradictory.
