Yin Yang Charm by Rembrandt Charms

In Chinese philosophy, yin and yang (simplified Chinese: 阴阳; traditional Chinese: 陰陽; pinyin: yīnyáng) are generalized descriptions of the antitheses or mutual correlations in human perceptions of phenomena in the natural world, combining to create a unity of opposites in the theory of the Taiji. The term liang yi (simplified Chinese: 两仪; traditional Chinese: 兩儀; pinyin: liǎngyí, lit. “two mutually correlated opposites”), also known as Yin and Yang or earth and heaven has a similar meaning.

The concept of yin and yang (or earth and heaven) describes two opposing and, at the same time, complementary (completing) aspects of any one phenomenon (object or process) or comparison of any two phenomena. They are universal standards of quality at the basis of the systems of correspondence seen in most branches of classical Chinese science and philosophy, traditional Chinese medicine being an example.
