I really did take three years reading this - one short lecture at a time. I feel I have a somewhat better understanding of what Zen Buddhism is about, which is probably the most one can ask of a book about a tradition that isn't really mine.

One theme that really struck a chord is that there isn't a distinct compartment into which one puts "practice" or "spirituality", any more than there is for "morality" or even "breathing" - to take these things seriously to make them a ubiquitous part of life. I often need reminding of this.
