Yin and Yang

Ancient Chinese philosophers, through close observation of nature and the universe, recognized the existence of two opposing forces—yin and yang. These two forces operate in opposition, yet they are complementary and interdependent.

This original Chinese philosophy considered the Theory of Yin and Yang as the fundamental law of the universe. Yin and yang can be seen in all aspects of nature, including human society. Without the existence of bad, there would be no good; without hatred, there would be no love. Yin and yang were also recognized in the polarities of day and night, cold and hot, man and woman, victory and defeat, and so on.

Yin refers to the energy of the moon. It is quiet, passive, serene, gentle, and nurturing. Yin is needed to balance Yang. Yin meridians indirectly connect to the ear through their corresponding Yang meridian. Yin is the parasympathetic nervous system.

Yang refers to the energy of the sun/daylight, positive, energetic, forceful, powerful. Yang meridians have direct connections to ear acupuncture points. Yang is the sympathetic nervous system.
