Just like in your country, the hippies. The hippies means negation of a positive materialistic life. That's all. Negation. They are simply denying that, "I . . . we don't want the way of life as our father and grandfathers are going on." That's a negation. But there is no positive gain. So negation is no good. You must have some positive gain. So our this Kṛṣṇa consciousness movement is negation of the materialistic way of life and regain the blissful, eternal life of spiritual understanding.
So simply negation is no gain. With something if you are disgusted, "I don't want it," but . . . just like sometimes a man commits suicide, "I don't want this life." So what is the gain? And that is ignorance. He does not know that committing suicide . . . he's eternal. He's eternal. Living entity is eternal. He thinks that "By killing this body, I am free from this bodily miserable condition of life." No. He's immediately . . . either he has to accept a next abominable body or he'll have to become a ghost, one who commits suicide.
Ghost means no material gross life, but the mental . . . material subtle life is there. A ghost is carried by the subtle body: mind, intelligence and false ego. And one who gets a body, gross body . . . upon this mind, intelligence and ego, one develops a gross body of five elements: earth, water, air, fire. This is the two kinds of body, a condition. And when he's actually Kṛṣṇa conscious, he's transcendental to this gross and subtle body. He attains a spiritual body, which is never to be finished—eternal, blissful life.
