The yin-yang symbol shows the opposite, balanced forces of the universe important in Taoism. Yin and yang are in tension, but they are not in opposition to each other. When both yin and yang are equally present, all is calm. When one is outweighed by the other, there is confusion.
Even in this symbol, the dark, yin side has a spot of white. The light, yang side has a spot of black. According to Taoism, nothing is absolutely dark or bright, good or bad. Everything contains both yang and yin.
Do you think this symbol conveys the idea of opposite, but balanced, forces?
