 Each facet of the “body” mentioned above requires the other two, but the variety of concepts embraced by these terms raises the question of which among them is at the center of the Daoist discourse. It could hardly be said that Daoism focuses on the physical body: as shown below, several loci at the basis of Daoist practices—for instance, the three Cinnabar Fields (dantian)—do not even exist at the purely physical level. In other cases, the loci at the basis of Daoist practices have corporeal counterparts, but their emblematic functions are more significant than those performed by the body parts themselves. The main example is the five viscera (wuzang). In its discourse on the viscera, Daoism shows little or no interest in the physical organs per se; the viscera serve, instead, as material supports for the network of correspondences that tie the human being to its immediate and remote surroundings: society and cosmos.
