This book brings together an impressive group of scholars to critically engage with a wide-ranging and broad perspective on the historical and contemporary phenomenon of Zen. The structure of the work is organized to reflect the root and branches of Zen, with the root referring to important episodes in Chan/Zen history within the Asian context, and the branches referring to more recent development in the West. In collating what has transpired in the last several decades of Chan/Zen scholarship, the collection recognizes and honors the scholarly accomplishments and influences of Steven Heine, arguably the most important Zen scholar in the past three decades. As it looks back at the intellectual horizons that this towering figure in Zen/Chan studies has pioneered and developed, it seeks to build on the grounds that were broken and subsequently established by Heine, thereby engendering new works within this enormously important religio-cultural scholarly tradition. This curated Festschrift is a tribute, both retrospective and prospective, acknowledging the foundational work that Heine has forged, and generates research that is both complementary and highly original. This academic ritual of assembling a liber amicorum is based on the presumption that sterling scholarship should be honored by conscientious scholarship. In the festive spirit of a Festschrift, this anthology consists of the resounding voices of Heine and his colleagues. It is an indispensable collection for students and scholars interested in Japanese religion and Chinese culture, and for those researching Zen Buddhist history and philosophy.
