In Chinese philosophy the Absolute is often represented by a simple symbol: a plain white circle surrounded by a plain black line. Out of the Absolute comes forth a point. This point is the World-Mind. With it there simultaneously manifests what the Bhagavad Gita calls the pairs of opposites and what the Chinese call yang and yin. Yang is symbolized by a kind of white crescent with a black dot in the broader end, yin by a black crescent with a white dot. It is not exactly a crescent because one end swells out like a balloon, while the other end remains sharp and pointed like a crescent. When the two symbols are put together in a single picture surrounded by the circle of the Absolute they form a single but complete symbol of the All. The Chinese call it the Tai-Ki. In Indian philosophy the Absolute is called Nonduality and the polarized universe is called Duality--or to be more precise Advaita, meaning the not two, and Dvaita, meaning the two. Yang is considered to be the positive element and yin the negative one; there is nothing in the universe which is not subject to the tension between these two elements. Therefore we human beings, who are part of the universe, are also subject to them. Their interaction brings about birth, life, and death.
