This text provides a comparative investigation of the affinities and differences of two of the most dynamic currents in World Buddhism: Zen Buddhism and the Thai Forest Movement. Defying differences in denomination, culture, and historical epochs, these schools revived an unfettered quest for enlightenment and proceeded to independently forge like practices and doctrines. The author examines the teaching gambits and tactics, the methods of practice, the place and story line of teacher biography, and the nature and role of the awakening experience, revealing similar forms deriving from an uncompromising pursuit of awaking, the insistence on self-cultivation, and the preeminent role of the charismatic master. Offering a pertinent review of their encounters with modernism, the book provides a new coherence to these seemingly disparate movements, opening up new avenues for scholars and possibilities for practitioners.
