Mystic yogis, by the practice of mystic or psychic powers, can do things that ordinary people consider very wonderful and miraculous. Such yogis then exploit the people, claiming that they are God Himself. And millions of foolish people believe such charlatans and blindly follow them. This is very unfortunate.
If the passing away of the body meant the end of your existence, then you, the self who existed along with the “childhood” body, should have ceased existing when that “childhood” body ceased to exist; and you, the self who existed along with the “adolescent” body, should have ceased existing when your “adolescent” body ceased to exist. The fact that you continued to exist, even though your body (bodies) did not, proves that your existence does not depend upon the continuing existence of a body.
Many Chinese and Japanese acupuncturists (possibly out of a desire to “prove” the existence of chi to skeptical Westerners) have invented all sorts of electrical technological gadgetry to monitor the flow of chi through the meridians and to precisely locate the acupuncture points. So although chi cannot be perceived directly, its presence can be detected by a meter that monitors electrical activity.
Unfortunately, most of humanity spends the majority of its time in the culture of ignorance. We cultivate ignorance by serving our tongue, belly, genitals, and other senses like obedient slaves. The vast majority of our energy goes into this mad pursuit of sense pleasure. Left with frazzled nerves, frustration, anger, jealousy, envy, greed, hate, loneliness, and confusion; we seek an escape in alcohol, cocaine, heroin, and a myriad of other legal and illegal consciousness dimmers. This is the cultivation of ignorance.
Everyone is engaged in action. The law of karma means that there are reactions to every action and that a person must endure the reactions to his actions.
So knowing who you are is a very practical necessity. The question “Who am I?” is not a philosophical football meant to be kicked around coffeehouses by pseudo-intellectuals. It’s a real-life question. Nothing is more important and more relevant than to know who you are.
If you know that you aren't your senses, you won't automatically conclude that what your senses want is what you want. You'll know that what your senses may want may not be good for you.
"There is more than enough food, water, fuel and so on to satisfy the actual needs of everyone on the planet. But there is not enough to satisfy everyone's greed. Even if it were physically possible for you to consume all the food water and fuel in the world, you still would not be satisfied " "material food" cannot satisfy spiritual craving. Since the materialist is never satisfied, he never feels that he has had enough."
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 at 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.
The body is yours — but it is not you. The body is a garment that you are wearing, a machine that you are using, a vehicle that you are driving. The body is your possession. Just as a person does not identify himself as being the shirt he is wearing, he also should not identify himself with the body that he is wearing.
