Yin Yang :
In Chinese philosophy, the concept of yin yang is used to describe how seemingly opposite or contrary forces are interconnected and interdependent in the natural world; and, how they give rise to each other as they interrelate to one another.
Many natural dualities such as: light and dark, high and low, hot and cold, fire and water, life and death etc.. are thought of as physical manifestations of the yin-yang concept.
