Twins

Between heaven and earth flows the energy of yin and yang. The human body also contains energy. This energy is wondrous: it can create or destroy. Those skilled at manipulating it have many energy points within their bodies, up to 316 at most. These points are interconnected, and the more there are, the more smoothly one can draw in and circulate energy. Why describe energy in such detail? Because this is a world of energy!
