Yuán-dynasty Quánzhēn 全真 master and Daozang commentator, zì Dàoyuán 道淵, hào Hùnránzǐ 混然子. Author of Tàishàng shēngxuán shuō xiāozāi hùmìng miàojīng zhù 太上昇玄說消災護命妙經註 (DZ 101), a Quánzhēn-school inner-alchemy commentary on the Táng Shēngxuán xiāozāi scripture. Wáng’s reading deploys the dàoyòng 道用 (“the use of the Dào”) vs. shìfǎ 世法 (“the method of the age”) distinction to contrast internal-alchemical interpretation with literal religious recitation — a characteristic Quánzhēn hermeneutic procedure also used by Chén Zhìxū. His commentary represents the influence of Neo-Confucian tǐ/yòng 體/用 dialectics on Yuán Daoist exegesis. No CBDB record was found. Wáng’s alchemical vocabulary aligns with the Quánzhēn school’s inner-alchemical idiom; he is quoted by Isabelle Robinet and others in Yuán nèidān studies.
