The Yellow Emperor Chapter 41 - The Spiritual Pivot – Yin and Yang Linked to Sun and Moon 阴阳系日月

This Chapter from The Yellow Emperor's Classic of Internal Medicine explores the correspondence between macrocosmic principles (heaven/earth, sun/moon) and the human body's meridians and organs. Qi Bo explains how the twelve leg meridians relate to the twelve months, and the ten hand meridians relate to the ten sun cycles, reflecting yin and yang distribution. The text details specific meridian associations with months and describes how this knowledge guides acupuncture treatment, emphasizing seasonal variations in qi flow. Finally, it clarifies that these correspondences reflect the dynamic interplay of yin and yang, rather than a strict adherence to the five-phase theory.
