Devotee: Śrīla Prabhupāda, I can't understand why we should have an impure desire when we are already serving . . .
Prabhupāda: Because you have got little freedom. Why one is not coming here and going to the liquor shop? It is his desire. Because he has associated with a different type of material quality . . . the same man who was drinking, now, as soon as they come in our association, he becomes a saint. Why? The American government spent millions of dollars to stop this habit of intoxication, LSD. And as soon as the same man comes to our Society, he immediately gives up. Why? It is practical. Immediately. At the initiation time we ask that, "You don't touch all these things." "Yes." That's all. See practically. Especially in the Western countries they are habituated to all these things: meat-eating, illicit sex, intoxication, gambling. How they give it up? Association. We are opening so many branches all over the world to give opportunity of association. It is not a business firm. Just to give spiritual association, chance. Why you are going the street saṅkīrtana? We are giving chance, "Come here, be saved." It is not business.
So this Kṛṣṇa consciousness movement is the topmost philanthropy, welfare activities to the human society. Those who are intelligent, they are understanding. Kāraṇaṁ guṇa-saṅgo 'sya sad-asad-janma-yonisu (BG 13.22). Others, they are associating with different qualities of the material nature, and nature is prepared, "Come on, sir, you take this body." You are not scientist, so-called scientist can save you. When this body is finished, then you are under the control of material nature. Whatever body she will offer you, you have to accept. You cannot say: "No, no. I cannot accept this body." "No, no. You are nothing. You are under my grip." You have asso . . . just like you contaminate with some infectious disease, you must suffer from that disease.
