Perfect for people who are interested in Yin and Yang / Taoism - 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. - wikipedia
