Most concepts of TCM are new to Westerners, but many have at least heard the words 'yin & yang' and have seen the tai chi symbol that represents this foundational concept of Chinese medicine.The tai chi symbol (pronounced like the words "tie chee") represents the ancient Chinese understanding of how the universe operates. The outer circle represents 'everything', while the dark & white shapes within the circle represent the interaction of two energies, called 'yin' (dark) & 'yang' (white). These two energies cannot exist without the other & cause everything to happen in the universe.
The concept of yin & yang is still used today & in many forms. Modern day physics uses this concept in much of the same way the Chinese did thousands of years ago when the idea was first invented. Physicists describe energy that is stored or inactive as potential energy, while this passive energy would be considered yin in TCM; energy that is being released is described by scientists as kinetic energy or would be considered yang in TCM. As you can see, there are many similarities in the way Easterners & Westerners describe the interactions in our world.
