"Cyber Zen is the first book-length ethnography of Buddhism practice in a virtual world. Grieve’s book offers an innovative theoretical approach and a fascinating exploration of the intersection of digital media, Buddhism, and popular culture. This is a valuable study of importance to anyone interested in digital religion, religion and media, Buddhism, and contemporary religion." - Erica Baffelli, University of Manchester, UK"Innovative virtual world spiritualties are likely to increase. With his deep understanding of traditional Buddhism and cybernetics, Grieve is well equipped as a guide through this dynamic intersection of Zen and digital media. We need more studies like this one to understand digital spirituality both in terms of contemporary culture and the evolution of religion."- Calvin Mercer, East Carolina University
