Becoming angry means you have lost your center. When you compete in a sport such as a martial arts tournament, you should not be angry with yourself for losing. Remaining centered means putting things in perspective. Learning from a loss, or a victory, should be the goal. Enjoying the moment and the competition with others is the way to remain centered.
Defeat is a path to the truth.
Learn from it. Only by remaining centered can you recognize your connection to all things and act accordingly no matter what situation arises. According to ancient Chinese theory, your physical center is located inside your body, three fingerwidths below your navel and two fingerwidths inside your body. It is here that Chinese science believes your internal energy, or chi, is stored. From your Dan Tien, chi circulates through acupuncture meridians to all parts of your body.
