Yin/Yang Double Dragon

In Asian philosophy, the concept of yin yang is used to describe how polar opposites or seemingly contrary forces are interconnected and interdependent in the natural world, and how they give rise to each other in turn. Opposites thus only exist in relation to each other. The concept lies at the origins of many branches of classical Chinese science and philosophy, as well as being a primary guideline of Traditional Chinese Medicine. The symbol is also and a central principle of different forms of Chinese martial arts and exercise, such as tai chi and gigong. Many natural dualities—e.g. dark and light, female and male, low and high, cold and hot, water and fire, air and earth— are thought of as manifestations of yin and yang (respectively).
