Book excerpt: Jeffrey L. Broughton here offers a study and partial translation of Core Texts of the S&on Approach (S&onmun ch'waryo), an anthology of texts foundational to Korean S&on (Chan/Zen) Buddhism. Core Texts of the S&on Approach provides a convenient entrée to two fundamental themes of Korean S&on: S&on vis-à-vis the doctrinal teachings of Buddhism (in which S&on is shown to be superior) and the huatou (i.e., phrase; Korean hwadu) method of practice-work originally popularized by the Song dynasty Chinese Chan master Dahui Zonggao. This method consists of "raising to awareness" or "keeping an eye on" the phrase, usually No (Korean mu). No mental operation whatsoever is to be performed upon the phrase. One lifts the phrase to awareness constantly, when doing "quiet" cross-legged sitting as well as when immersed in the "noisiness" of everyday life. Core Texts of the S&on Approach, which was published in Korea during the first decade of the twentieth century (the identity of the compiler is not known for certain), contains eight Chan texts by Chinese authors (two translated here) and seven S&on texts by Korean authors (three translated here), showing the organic relationship between the parent Chinese tradition and its Korean inheritor. The set of translations in this volume will give readers access to some of the key texts of the Korean branch of this influential East Asian school of Buddhism.
