Once you become aware of your own body and its movements, you will be surprised that you are not your body. This is something of a basic principle, that if you can watch something then you are not it. You are the watcher, not the watched. You are the observer, not the observed. How can you be both?
It is almost as if the millennium were arrived, when we shall throw our clocks and watches over the housetop, and remember time and seasons no more. Not to keep hours for a lifetime is... to live forever.
