Interdependent: Can not exist without each other The Tai Ji (Supreme Ultimate) diagram shows the relationship of Yin & Yang and illustrates interdependence on Yin & Yang. Nothing is totally Yin or totally Yang. Just as a state of total Yin is reached, Yang begins to grow. Yin contains seed of Yang and vise versa. They constantly transform into each other. For Example: no energy without matter, no day without night. The classics state: “Yin creates Yang and Yang activates Yin”.
Inter-transformation of Yin and Yang. One can change into the other, but it is not a random event, happening only when the time is right. For example: Spring only comes when winter is finished.
