Цюаньчжэнь
During the Song Dynasty (960-1260 CE), the "Qingjing Jing" became popular within the Southern Lineage "Complete Perfection" or Quanzhen School and was interpreted in context with "neidan" Chinese internal alchemy. For instance, the seventh Quanzhen master Sun Bu'er took Qingjing sanren "Vagabond of Clarity and Quiescence" as her sobriquet and established the Qingjing Sect (Miura 2007:800). Modern Quanzhen Taoists consider the "Qingjing jing" a central scripture and regularly chant it in "songjing" (, "reciting scriptural passages; ritual recitation"). Kohn explains.
