“Truth is something which must be known with the mind, accepted with the heart, and enacted in life”
The principle of yin and yang is the fundamental concept of Traditional Chinese medicine. It is an all embracing idea that can be used to describe virtually all natural occurrences.
It could be said that all Chinese medical physiology, pathology, and treatment, can eventually, be reduced to Yin-Yang. Therefore, so can the concept of preventative health be reduced to Yin-Yang. The concept of Yin/Yang is extremely simple, yet very profound.
In general Western logic is based on the opposition of contraries. The Chinese concept is a system of thought that Yin and Yang represent opposite but complimentary qualities. Or as represented in the Yin/Yang symbol. There is the seed of Yang in Yin and vice versa.
