The Book of Equanimity contains the first-ever complete English language commentary on one of the most beloved classic collections of Zen teaching stories (koans), making them vividly relevant to spiritual seekers and Zen students in the twenty-first century. Continually emphasizing koans as effective tools to discover and experience the deepest truths of our being, Wick brings the art of the koan to life for those who want to practice wisdom in their daily lives. The koan collection Wick explores here is highly esteemed as both literature and training material in the Zen tradition, in which koan-study is one of two paths a practitioner might take. This collection is used for training in many Zen centers in the Americas and in Europe but has never before been available with commentary from a contemporary Zen master. Wick's Book of Equanimity includes new translations of the preface, main case and verse for each koan, and modern commentaries on the koans by Wick himself.
