Baozang lun; 1 fasc.， Attributed to Sengzhao 僧肇. The Baozang lun is stylistically and doctrinally similar to a number of texts associated with the Ox-head 牛头 Chan lineage， notably the Jueguan lun， Xinxin ming 信心铭， Xin ming， Wuxin lun， and so on. It also appears to be related to a group of seventh- and eighth-century Daoist commentaries and scriptures later classified under the heading chongxuan （"double mystery"）. Like the Ox-head and chongxuan materials， the Baozang lun is a synthesis of Daoist 老庄 metaphysics and Buddhist Madhyamika 中观派 dialectic. It is notable for its ruminations on concepts such as "true one" （zhen'i 真一）， "point of origin" （benji ）， no-mind （wuxin 无心） etc.， and is the locus classicus for the pairing of "transcendence" and "subtlety" （li 离 and wei 微）. It also contains a critique of Buddha invocation practices （nianfo 念佛）， and a positive reference to the doctrine that even insentient things have buddha-nature 佛性. T 1857.45.143b-150a.
