The book focuses on the history of Zen Buddhism and Japanese militarism from the time of the Meiji Restoration through the Second World War and the post-War period. It describes the influence of state policy on Japanese Buddhism, and particularly the influence of Zen philosophy on the Japanese military. A famous quote is from Harada Daiun Sogaku: [If ordered to] march: tramp, tramp, or shoot: bang, bang. This is the manifestation of the highest Wisdom [of Enlightenment]. The unity of Zen and war of which I speak extends to the farthest reaches of the holy war [now under way]
