I've been reading this book (found by accident at the library), by Hakuun Yasutani Roshi, and I'm loving it. What a fiery teaching and cutting insight! He minces no words when it comes to cutting down what he saw as the lazy dogmatic views and infighting of the usual Zen schools...
I'm finding his commentary really useful in my understanding, I think I'll be re-reading it several times. I like his passionate emphasis on experiencing Dogen's words and the way various verses work at different levels for different readers. Wondering if anyone else has read it?
