Abstract
Zen Buddhism often appears to be ‘anti-intellectual’, ‘illogical’ and ‘trivial’. These apparent aspects of Zen have puzzled many students of Buddhism. Why is Zen so ‘irrational’? By what Buddhist doctrines, tenets or philosophies did Zen masters develop their unconventional and dramatic teachings and practices? The aim of this paper is to show that main San-lun Mādhyamika doctrines, such as Emptiness, the Middle Way, the Twofold Truth and the refutation of erroneous views as the illumination of right views, have been assimilated into Zen teachings and practices Mādhyamika philosophy seems to provide a major ‘theoretical’ foundation for as a ‘practical’; ‘anti-intellectual’, ‘irrational’, ‘unconventional’ and ‘dramatic’ religious movement.
