One of the strangest books I've ever read. The original Japanese title is absolutely brilliant -
Gendai sōjizen hyōron - Contemporary Pseudo-Zen Critique. Written by an anonymous monk in 1916 who, Hoffmann reckons, was extremely learned and deep into one Zen sect or another, it aimed to reveal the shallow basis of the koan traditions through the publication of the answers to these famous paradoxes.
I'm not an expert on Zen, but I thought I knew a thing or two, and I certainly hadn't known that koans were supposed to have answers. Specific answers, not personal interpretations that illustrate a deeper spiritual understanding of what is implied.
The answers are likely to be controversial. By which I mean, it is impossible not to read this book and not find the answers stupid. You will find your appreciation of Zen shrink and depreciate. You will relate to the Japanese author who felt it necessary to expose the bullshit.
With that understanding in mind, you may appreciate the translator, who had an especially difficult job in translating these opaque and esoteric koans and their insipid answers. A true believer would try to frame things in the best light possible, while a polemicist would strive to expose the pseudo-Zen in fierce English. The book, instead, is a strange mixture of genuine provocative, insightful koans, and the baggage of tradition and hierarchy. I have never really been into Zen because, although I am fascinated by Buddhism, Zen has always connotated the worst aspects of Japanese culture - blind unyielding obedience to superiors, the vanity of purity, vague anti-humanism...it seemed to put itself above the 'Buddhist' parts of Buddhism. As its own thing, though, I have enjoyed studying it, even if it is not the path for me, or for most.
