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.
Interviewer: There has been a lot of talk of genetic perfection of mankind, or, say, attempting a genetic perfection.
Prabhupāda: What is genetic?
Interviewer: What is genetic perfection?
Bali-mardana: We were discussing yesterday about the science of genetics. They try to understand the traits, how the body and mind are formed, and then try to change it.
Prabhupāda: That we have already . . . where is that book?
Rāmeśvara: Svarūpa Dāmodara's book.
Prabhupāda: Yes. Bring.
Rāmeśvara: Well, what is your question?
Interviewer: My question is . . . you were mentioning earlier about using the technological tools, and if there is some society where there is some . . .
Prabhupāda: That book is not here? Nowhere?
Interviewer: Let me ask you. If through technological means mankind is somewhat improved, in other words, the average man is much more intelligent, what you would consider now to be an intelligent man . . .
Prabhupāda: But intelligent man . . . if one understands that he is not this body—he is within the body . . . just like you have got one shirt. You are not the shirt—anyone can understand—you are within the shirt. Similarly, a person who understands that he is not the body—he is within the body . . . that anyone can understand, because when the body is dead, what is the difference? Because the living force within the body is gone, therefore we call the body dead.
