Prabhupāda: This is lack of Kṛṣṇa consciousness. Therefore Kṛṣṇa consciousness education is greatly needed for human society. Do you follow, Guru dāsa?
Guru dāsa: Yes.
Prabhupāda: So you have to convince people like that, that it is not a sentimental institution. We are teaching the thing which is very absolutely needed for the human society. As soon as one becomes Kṛṣṇa conscious, his personal questions and problems are solved. And if others adopt the same principle, then social-political questions are also solved. So we have to teach. They will say it is not practical. Why not practical? No, anything is not, not practical. There are so many scientific... You discovered. Just like this tape recorder. This is advantageous to the human society. But it is not practical that everyone will have a nice tape recorder. That is not practical. But when you go to manufacture, say the discoverer, "Oh, that it is not practical; therefore it should not be manufactured." Similarly, Kṛṣṇa consciousness may not be practical for all, but that does not mean it should not be preached. The customer will take. Just like this tape recorder, one has got money, you have purchased, taking advantage. Similarly, there are many pious persons who can take Kṛṣṇa consciousness. Just like you have taken. You are not ordinary common men. There must have been some pious activities in your past lives. Therefore you have taken to this Kṛṣṇa consciousness seriously.
