Description

Yin and Yang are concepts of the Taoism that expose the duality of everything that exists in universe. They describe the two fundamental opposing and complementary forces found in all things: the yin is the principle of night, Moon, passivity, absorption. The yang is the principle of Sun, day, the light and activity.^[1]

According to this idea, every being, object or thought has a complement on which it depends for its existence. This complement exists within itself. Thus, it follows that nothing exists in a pure state: neither in absolute activity nor in absolute passivity, but rather in continuous transformation. Furthermore, any idea can be seen as its opposite when viewed from another point of view. In this sense, categorization would be for convenience only. These two forces, yin and yang, would be the next phase of the “so“, generating principle of all things, from where they arise and where they are destined.

This doctrine is in common use in Traditional Chinese Medicine.

In the studies of I Ching, there are two Initial Lines generated by Tai Ji, one Whole Yang and one Broken Yin, forming the Liang Yi.
