YIN & YANG ARE RELATIVE OPPOSITES  All that exists can be described as yin and yang  Every thing is in relation to something else, like day and night  Physical activity is yang (daytime) rest is yin (night time).  The health of the universe and human beings relies on the continuous, shifting, cyclical movements of these relative opposites.

YIN & YANG ARE INFINITELY DIVISIBLE  Things change depending on what is happening around them, e.g. a candle when lit; the flame is yang and the candle yin  If this candle were then placed in a dark room the whole candle would be yang  but if placed next to a fire the candle would be yin next to the greater yang of the fire

YIN & YANG ARE INTERDEPENDENT  Yin cannot exist without yang and vice versa, no light without dark, no contraction without expansion  Just as the earth needs rainfall (yin) and dryness (yang) to survive, the relationship of these two energies are vital in the body.

Yin & Yang consume and support each other YIN & YANG CONSUME & SUPPORT EACH OTHER  The balance between yin and yang is not fixed but a continually moving, shifting dynamic interaction, night consumes day, summer consumes winter.  If one becomes weak it cannot support the other.  If one becomes excessive it may over consume the other.

YIN & YANG TRANSFORM INTO EACH OTHER  As in Inhalation/exhalation.  Or Activity followed by rest.  To continue functioning, all energy systems must achieve a balanced state of equilibrium between input and output.

Balance is harmony  All diseases and disharmonies are due to an imbalance of yin and yang energies within human beings.  If yang becomes deficient the person will manifest symptoms associated with yin, such as weakness and coldness as yin appears dominant.  If yin becomes deficient then yang symptoms will manifest such as feeling hot and agitated with difficulty sleeping.
