Prabhupāda: No, no, in science there are two con..., theoretical and practical. So theoretical knowledge is no perfect. When you bring it in practical action, then it is science. In the scientific laboratory, they do not simply theorize; they test it in the laboratory. That is science. If you cannot test it by combination of the chemicals which you have analyzed in your..., then it is failure, is it not?
Svarūpa Dāmodara: Yes.
Prabhupāda: Here is a scientist. You have not studied properly. That is defect. So why defective knowledge you are declaring as knowledge? That is cheating. When you have perfect knowledge, then you declare. That is science.
Mr. Boyd: Then you advocate that Kṛṣṇa consciousness should be practiced in every action that you take.
Prabhupāda: Yes. Everything is practice. Abhyāsa-yoga-yuktena cetasā nānya-gāminā (BG 8.8).
Svarūpa Dāmodara: Scientists at the present time, they say like this because their knowledge is simply illusion.
Prabhupāda: Yes.
Svarūpa Dāmodara: Real knowledge is covered.
Prabhupāda: Just like this planetary system. So many planets are there. They do not know anything. And they are going to the Mars. They are going to the moon. All bluff. Two things unsolved. They do not know what is life and they do not know what are these planetary system. And still, they are speaking on these two subjects as authority. That is bluff.
Svarūpa Dāmodara: So we conclude that without understanding the existence of God, these two problems can never be answered.
Prabhupāda: Never be. You hear from God; then you have got perfect knowledge. And if you want to become scientist more than God, then you'll never know it. But their real propaganda is "There is no God." That is their real propaganda.
Svarūpa Dāmodara: That is the root cause of this illusion.
Prabhupāda: Yes. They want to prove "There is no God. Everything is science." However rascaldom it may be, "It is everything." But we are preaching about God. How we can tolerate? We must expose them. That is our business.
