The Dongshen sanhuang jing, referring to the immortals of the Western Regions, says: "Huangwen (Sovereign Script) was the writing at the very beginning of bird tracks prior to the Three Sovereigns." It also says: "The Three Sovereigns are the revered spirits of the Three Caverns, the ancestral qi of the Great Existence. The Heavenly Sovereign presides over qi; the Earthly Sovereign presides over spirit; the Human Sovereign presides over birth. The three unite to complete virtue, and the myriad things are transformed and generated."
