 The center of the human being is represented in different ways; and not being material, it may have different symbolic locations and names. Most important among them is the Heart (xin, a word also meaning “center”). Related images and terms include the Yellow Court and the Mysterious-Female. The Yellow Court (huangting, where “yellow” is the color of the central agent Soil, and the “court” is the central courtyard in traditional Chinese houses) has different definitions. When the framework of reference is the three Cinnabar Fields, it may denote any of them, and especially the central one, corresponding to the heart; when it is the five agents, it denotes the spleen, which is placed at the center of the five viscera and corresponds to Soil. The Mysterious-Female (xuanpin, a term derived from the Daode jing and often translated as “mysterious female”) is the immaterial locus of the conjunction of Yin (the “female”) and Yang (the “mysterious”).
