Prabhupāda: When he speaks. Tāvac ca śobhate mūrkho yāvat kiñcin na bhāṣate: "A fool is so long beautiful as long as he does not speak." (laughter) When he speaks, then you can understand what he is. So my speaking are there in the books, and if you are intelligent, you can understand. You haven't got to ask. Speaking . . . just like in a court. A big lawyer is known when he speaks. Otherwise everyone is a good lawyer. But when he speaks in the court, then he is known whether he is good lawyer or not. So you have to hear. You have to read. Then you'll understand. Real understanding is there.
Interviewer: Do you think that some day the Kṛṣṇa consciousness movement will spread to all the people in the world?
Prabhupāda: That is not possible. It is more for the most intelligent class of men. So it, this movement, is for the most intelligent class of men.
Interviewer: But amongst the most intelligent classes.
Prabhupāda: Unless one is intelligent class, belonging to the in . . . he cannot understand. So we don't expect that everyone is intelligent. Kṛṣṇa yei bhaje se baḍa catura (CC Antya 4.67). Unless one is very intelligent, he cannot become Kṛṣṇa conscious, because it is a different subject matter. People are engrossed with the bodily concept of life. It is beyond that. So dull brain cannot understand what is beyond this body. So you cannot expect that everyone will understand Kṛṣṇa consciousness. That is not possible.
