Dao, Yin and Yang

Dao and Yin Yang Theory

Dao can be explained into a route of the truth in Chinese Dao school. The Chinese ancestors observed the universe and  inducted the Dao and Yin-Yang theory to explain the truth of life and the Universe. Dao is the complete whole of Yin and Yang. Which means everything in the universe contains Yin and Yang, and only when Yin and Yang balanced and harmonized, everything in the universe will  exist as the state of perfection and wellness.

The early theory of yin-yang was formed thousands and thousands years ago in Ancient China. The term yin-yang first appeared in The Book of Changes, “Yin and yang reflect all the forms and characteristics existing in the universe. Up to the Spring and Autumn Period (770-476 B.C.) and the Warring States Period the application of the theory of yin-yang had been deeply rooted in all schools of thought. It was pointed out in the book “Plain Question of the Yellow emperor classic”: “Yin and yang are the laws of heaven and earth, the great frame- work of everything, the parents of change, the root and beginning of life and death…. This quote expresses the idea that all natural events and states of being are rooted in yin and yang.

Yin and Yang may look like the two opposition, but they are coexisting, corresponding and corestraining. They can’t survive without each other, there generate and control each other. In Oriental Medicine, physiology and pathology of the human body state “ The Functions of Yin is the material baais for yang, and Yang is the functional manifestation of yin.” “An excess of yang implies a deficiency of yin and vice versa.” But in the chronic conditions, a deficiency of one aspect does not always cause an excess of the opposite aspect. In extremely chronic conditions there is usually a deficiency of yin and yang, It is almost impossible to see a case of an excess simultaneously of both yin and yang. In the case of deficiency of both yin and yang, to tonify either aspect will benefit the opposite aspect. Yin and Yang need to be balanced, otherwise sickness will occur.
