Prabhupāda: To copy in hand, how long it takes? Very big book?
Pradyumna: No. Not so big. And they also have that paṇḍita who used to live with Bhaktivinoda? They had that tall Sarasvatī, that Sarasvatī Catuspati . . . Bhaktisiddhānta . . . his name was . . . his books are also there, two, three books. They have published jointly from Saraswati Bhavan. Bhaktivinoda Ṭhākura . . . (indistinct)
Prabhupāda: So the scientists could not say anything.
Svarūpa Dāmodara: Well, we said: "We are working on it." We were not giving a definite . . . 'cause we need some proof to satisfy them. So we are . . .
Prabhupāda: Anyway, you are meeting big, big scientists.
Svarūpa Dāmodara: But we are saying that our senses are very incomplete, very limited. So how can we . . .
Prabhupāda: That is our basic principle of knowledge, that every one of us is defective, so you cannot give us complete knowledge; it is not possible. We must receive knowledge from the perfect without defects.
Svarūpa Dāmodara: So we were bringing that and answering, not answering directly, but saying that whatever we see, whatever we find by experimental science, by these instruments, we see something, but how do we know that . . .? Our matter of receiving knowledge is by itself defective.
Prabhupāda: Defective, yes.
Svarūpa Dāmodara: Because actually there are many defects in science.
Prabhupāda: So they do not challenge you, that "How your knowledge is perfect?" They do not challenge that?
Svarūpa Dāmodara: No.
Prabhupāda: No, then they can challenge like that, that "If our knowledge is imperfect, how your knowledge is perfect?" If they challenge like that, what you will answer?
