Yuanshi Tianzun
In religious Taoism, the theory of how Tao produces One, Two, and Three is also explained. In Tao produces One—Wuji produces Taiji, it represents the Great Tao, embodied by Hundun (, "Heavenly King of the Chaotic Never-ending Primordial Beginning") at a time of pre-Creation when the Universe was still null and the cosmos was in disorder; manifesting into the first of the Taoist Trinity, Yuánshǐ Tiānzūn. Yuánshǐ Tiānzūn oversees the earliest phase of Creation of the Universe, and is henceforth known as Dàobǎo () "Treasure of the Tao". In One produces Two—Taiji produces Yin Yang, Yuanshi Tianzun manifests into Lingbao Tianzun who separated the Yang from the Yin, the clear from the murky, and classified the elements into their rightful groups. Therefore, he is also known as Jīngbǎo () "Treasure of the Law/Scripture". While Jīng in popular understanding means "scriptures", in this context it also mean "passing through" [the phase of Creation] and the Laws of Nature of how things are meant to be. In the final phase of Creation, Daode Tianzun is manifested from Língbăo Tiānzūn to bring civilization and preach the Law to all living beings. Therefore, He is also known as Shībǎo () "Treasure of the Master".
