Hekiganroku (E. The blue cliff record, C. Pi-yen-lu)
A collection of 100 koans originally compiled, with appreciatory verses, by Setcho Juken (C. Hsüeh-tou Ch'ung-hsien) under a name of the 'Priest Hsüeh-tou 's Capping Verses on One Hundred Cases'. Although it is a text of fundamental importance for koan study in the Rinzai School it was also studied by Eihei Dogen, the founder of the japanese Soto school, who on the return from Zen studies in China brought with him to Japan a handwritten copy of the document.
