Yin-Yang Theory
The theory of Yin-Yang holds that every object or phenomena in the universe
consists of two opposite aspects, namely, Yin and Yang, which are in
continual conflict and in interdependence. The relation between Yin and Yang is
the universal law of the world. For example, day and night, the day is
yang to the yin of night. Likewise brightness, warmth and movement belong
to yang, while the darkness, cold and stillness belong to yin.
