The creator was very very kind to us. The creator designed this universe with an infinite source of energy. It is as if you tried to drink all the ocean's water one spoonful at at time. The only problem is that we can tap the source but in acting strictly from the source we effectively shut it off. This has been verified thru quantum physics, and the teachings of the tao. A simple example would be, spin in a revolving chair, notice your speed, also notice how your speed increases as you bring yourself in closer towards the center of motion. In this example the center of motion is the source. You cary the same amount of energy with your extremities outstreched as when you are tucked in. However as you direct yourself towards the source(tucking your body in) your speed(energy) increases, and once you are tucked in you stop accelerating. The trick of tai chi is thru motion you direct yourself towards your center but never actually get there. It is perpetual motion directed towards your gravitational center. I have used this understanding and applied it to my martial art. The result: 2 holes in a concrete wall, in my house from a side kick and a punch.
