The Yin Yang doctrine is very simple but its influence has been extensive. No aspect of Chinese civilization-whether metaphysics, medicine , government, or art - has escaped its imprint. In simple terms, the doctrine teaches that all things and events are products of two elements, forces or principles: yin, which is negative, passive, weak, and destructive, and yang, which is positive, active, strong, and constructive. In Chinese philosophy , the concept of yin yang is normally referred to in the West as ''yin and yang'' and 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. Many natural dualities - e.g. dark and light, female and male, low and high, cold and hot - are thought of as manifestations of yin and yang(respectively). Yin yang are complementary opposites that interact within a greater whole, as part of a dynamic system. Everything has both yin and yang aspects, but either of these aspects may manifest more strongly in particular objects, and may ebb or flow over time.
