The tai shang dong xuan ling bao wu liang du ren shang pin jing zhu 太上洞玄灵宝无量度人上品经注

Commentary on the Supreme and Highest-Rank Scripture of Infinite Salvation from the Supreme Mysterious Numinous Treasure Originally attributed to Chen Chunrong as the compiler and annotator. With numerous citations of Emperor Huizong of Song’s "Zhenghe Imperial Commentary" throughout the text, it is presumed to have been composed in the late Northern Song or Southern Song Dynasty (c. 12th–13th centuries CE).

Five juan (scrolls), included in the Daozang (Taoist Canon) under the Dongzhenbu (True Grotto Section), Yujue lei (Jade Commentaries Category).

This commentary interprets the scripture with a primary focus on internal cultivation methods (neidan). The author divides the scripture into several sections, providing detailed annotations sentence by sentence and paragraph by paragraph, explaining recitation techniques and finger gestures (zhijue—ritual finger mudras used during scripture recitation). Interspersed within the textual annotations are the sixty-four I Ching trigrams, sundials, various diagrams, talismans, prayers, and mantras.

Later Taoist scholars such as Xiao Yingsou, True Person Qingyuan, and Zhang Yuchu were influenced by this work when compiling their own commentaries on the Duren Jing (Scripture for Saving Beings).
