Is Yin-yang That Mysterious?

Yin-yang is the most fundamental idea of TCM, the very first concept of it is from the ancient Chinese classic — “I Ching” or “The Book of Changes”. In which states that “Oneness” generates “Yin and Yang”, two opposite and contrary but complementary, interconnected, and interdependent forces in universe, they may give rise to each other as they interrelate to one another to cause change.

They are the symbol of the fundamental forces of universe, can be found everywhere and in everything. They are also symbiotic, neither Yin alone nor Yang alone is able to exist. For instance, shadow cannot exist without light.

We can also find many tangible dualities, such as light and dark, fire and water, expanding and contracting, front and back, positive and negative, etc, which are thought of as physical manifestations of the duality symbolized by Yin and Yang.

You may ask, what does TCM to do with Yin-yang? Well, what’s the best time of a day? Morning and dusk. What‘s the most comfortable water temperature? Warm, not cold either hot. Why is that? Because it’s the balanced status of Yin and Yang. So is the human body. Bringing back the balance of your Yin and Yang is exactly what TCM does.
