Yuanshi Tianzun
As the Three Pure Ones are manifestations of Primordial Celestial Energy, they are formless. But to illustrate their role in Creation, they are often portrayed as elderly deities robed in the three basic colours from which all colours originated: Red, Blue and Yellow (or Green) depending on personal interpretation of colour origins by additive or subtractive means. Each of them holds onto a divine object associated with their task. Yuánshǐ Tiānzūn is usually depicted holding the Pearl of Creation, signifying his role in creating the Universe from void and chaos. The Ruyi held by Lingbao Tianzun represents authority: the second phase of Creation where the Yang was separated from the Yin and the Law of Things was ordered in place. Lingbao Tianzun then took his seat on the left of Yuanshi Tianzun. Later, when all was complete, Daode Tianzun took his place on the right, with the fan symbolizing the completion of Creation, and the act of fanning representing the spreading of Tao to all Mankind.
