An excerpt from Who Are You? Discovering Your Real Identity by Chris Butler
Often people try so hard to find happiness through sense pleasure that they may attempt to gratify several or all of their senses at the same time. For example, you may simultaneously be watching TV, listening to the radio, munching potato chips, sipping beer, and smoking a cigarette. Perhaps you may have your arm around the shoulders of your girlfriend or boyfriend. You may also have a magazine by your side, which you look at during commercials. You try to fill up every sense; yet still you're not satisfied; still you want something more.
You can eat so much food that your belly aches—yet you still want more! Even though your belly is filled to the point of physical pain, you, the self, are not full; you still desire to consume more. The fact that the body can be full or satisfied while you still feel empty is evidence that the body is not you.
