Riley’s Mandala of the Stomach Spleen and Pancreas This mandala demonstrates the earthly transforming and digesting energy of these organs, which are visualized in red at the center of the mandala. The yin-yang template ley-lines the map of the body from head to base. Each element is depicted with emphasis on the rising phoenix-bird coming out of the Shen of the spleen, and a dragon of the east for the cauldron of the stomach.
