Reading Dosho Port's review reminded me of some of the back and forth we have had here. It will never be "solved", but the topic can be interesting, I suppose.
Anyway, looking forward to reading it.Ford Rōshi’s new book is an excellent resource especially for students interested in exploring the kōan way AND for teachers and students of just-sitting Zen. My bet is that a careful read will dispel many myths about kōan work. Not that this book is the one and only way to see it – kōan work, like just-sitting Zen, has many flavors and focus points. And as always with us large-brained primates, to paraphrase Max Weber, there is more difference within the kōan group than between the kōan group and just-sitting Zen.
