Lopez, Jr., 124-48. Princeton: Princeton University Press, 1996. Categorized as a “miscellaneous” or “mixed-together” (za 雜) text under Han bibliographic categories, this anthology was traditionally ascribed to Master Guan, a minister of the state of Qi who died in 645 B.C.E. The core of the received edition dates to the 3rd century B.C.E. It includes some material that may be labeled “Daoist” or “proto-Daoist,” especially the so-called “Heart-Mind Techniques” (xinshu 心術) chapters: “Xinshu shang” 心術上 (Heart-Mind Techniques, Part I; ch. 13), “Xinshu xia” 心術下 (Heart-Mind Techniques, Part II; ch. 13), “Baixin” 白心 (Purifying the Heart-Mind; ch. 13), and “Neiye” 內業 (Inward Training; ch. 16). http://www.daoistcenter.org/texts.pdf
