Prabhupāda: If simply people become inquisitive, what is Kṛṣṇa, and you simply try to answer them—we have got so many books now—then the whole world will be peaceful. Yena ātmā suprasīdati. Everyone is hankering after, "Where is peace? Where is peace?" You know, you European and American boys. You have come to Kṛṣṇa consciousness because on account of your hankering, "Where is peace?" Is it not?
Devotee: Yes.
Prabhupāda: What is that? So you were, you were not after money; because money and woman, you have seen, enough. There is no scarcity of money and woman in Europe and America. You can earn any, as much as you like, and you can enjoy. But still, why they are coming out confused? They want something. That I have several times repeated, that your only qualification is, you are advancing in Kṛṣṇa consciousness because you are..., you have no other material desires. Anyābhilāṣitā-śūnyam (Brs. 1.1.11). Nobody can allure you by material inducements: "Oh, here is money. Please come. Here is woman. Please come." That you have seen. You want something... Paraṁ dṛṣṭvā nivartate (BG 2.59). So that's a very good qualification. Not only you who have come to me as my disciples—I am speaking of the whole Europeans and Americans.
So try to impress the whole Western world about kṛṣṇa-sampraśnaḥ. Then they'll be happy. That is our mission.
