Query: A good place to start, and come back to

Christian Zen is a good place to start for someone who is interested in Christian applications of Zen, but doesn't want to spend years researching it. It also has a lot of insights that are not apparent on a first read that make the book worth coming back to over and over again.If you're JUST looking for info on Zen, don't bother with this book,(it's about Christian applications of Zen). Try 3 Pillars of Zen by Philip Kapleau instead.
