Hakuin Enkaku Zenji (1686-1769) was one of the greatest Zen masters to ever live. In additional to being the author of the most famous koan ever written, “What is the sound of one hand clapping?” he is credited with reviving the Rinzai sect of Zen in Japan, perhaps the most important and most rigorous branch in the Golden Age of Buddhism. His “Song of Zazen” is chanted in monasteries daily all over the world. Hakuin taught that there are three essentials to Zen practice: Great Faith, Great Doubt, and Great Resolve. Only Dogen comes close to matching the power and breadth of his writing and teaching. Norman Waddell has spent his life reading and commenting on the vast work of Hakuin. He has published several previous selections, all leading to his work on this major, monumental gathering, the Keiso Dokuzui, never before translated in any foreign language. Translating sacred texts requires years of practice and intimate familiarity with the material in its original language, as well as complete mastery of the available commentary. There’s no one alive better capable of handling this important and difficult offering. For this collection Hakuin gathered more than 200 individual pieces, consisting of commentaries, memorials, poems, koans, and teisho (lectures). They were offered to the many students living around his temple as well as to the countless lay followers around the country, and Hakuin spent his life offering these teachings together with his own commentary. Result is an organic, growing collection of understanding and advice, certain to engage Zen students as well as religious practitioners in other spiritual disciplines
