Book excerpt: Awakening to Reality (Wuzhen pian) is one of the most important and best-known Taoist alchemical texts. Written in the eleventh century, it describes in a poetical form, and in a typically cryptic and allusive language, several facets of Neidan, or internal alchemy. The present book presents the first part of the text, consisting of sixteen poems, which contain a concise but comprehensive exposition of Neidan. In addition to notes that intend to clarify the meaning of the more obscure points, the book also contains selections from a commentary dating from the late eighteenth century, which is distinguished by the use of a lucid and plain language. ⿿ Fabrizio Pregadio has taught at the University of Venice (1996-97), the Technical University of Berlin (1998-2001), and Stanford University (2001-08). He is the author of Great Clarity: Daoism and Alchemy in Early Medieval China (Stanford University Press, 2006) and the editor of The Encyclopedia of Taoism (Routledge, 2008).
