In a Taiji Symbol, one side is yang the other is yin, and the curvature in the middle is the Taiji Cord. Taiji is derived from Wuji, the original nature of the Dao. If we compress a Wuji Symbol (a circle) then twist the compressed symbol (oval) it becomes a Wuji Twist (Wuji in a twist). Overlap the Wuji Symbol with the Wuji Twist and it becomes a representation of the Taiji Symbol (Drawing 2-1). The ability to reverse the twist and return it to its original nature is the way to the Dao.
