the Yin-Yang symbol or Taijitu, with black representing yin and white representing yang. It is a symbol that reflects the inescapably intertwined duality of all things in nature, a common theme in Taoism. No quality is independent of its opposite, nor so pure that it does not contain its opposite in aÂ diminishedÂ form: these concepts are depicted by the vague division between black and white, the flowing boundary between the two, and the smaller circles within the large regions.
Everything can be described as bothÂ yin and yang.
1.Â Yin and yangÂ are opposites.
Everything has its opposite – although this is never absolute, only relative. No one thing is completely yin or completely yang. Each contains the seed of its opposite. For example, winter can turn into summer; “what goes upÂ must come down”.
2.Â Yin and yangÂ are interdependent.
One cannot exist without the other. For example, day cannot exist without night. Light cannot exist without darkness.
3.Â Yin and yangÂ can be further subdivided intoÂ yin and yang. Any yin or yang aspect can be further subdivided intoÂ yin and yang. For example, temperature can be seen as either hot or cold. However, hot can be further divided into warm or burning; cold into cool or icy. Within each spectrum, there is a smaller spectrum; every beginning is a moment in time, and has a beginning and end, just as every hour has a beginning and end.
4.Â Yin and yangÂ consume and support each other.
Yin and yangÂ are usually held in balanceâ€”as one increases, the other decreases. However, imbalances can occur. There are four possible imbalances: Excess yin, excess yang, yin deficiency, andÂ yang deficiency. During the switch toÂ Daylight savingÂ time, for example, there is more ‘yin’ than ‘yang’. They can again be seen as a pair: by excess of yin there is aÂ yang deficiencyand vice versa. The imbalance is also a relative factor: the excess of yang “forces” yin to be more “concentrated”.
5.Â Yin and yangÂ can transform into one another.
At a particular stage, yin can transform into yang and vice versa. For example, night changes into day; warmth cools; life changes to death. However this transformation is relative too. Night and day coexist on Earth at the same time when shownÂ from space.
6. Part of yin is in yang and part of yang is in yin.
