About a year ago another member happened to mention Steven Hayes and ACT ("Acceptance and Commitment Therapy"). I liked what I read about it online so I bought his book (Get Out of Your Mind and Into Your Life) and read that, too. It was based on ACT and turned out to be all about applying mindfulness techniques in everyday life.

I kept thinking that most parts of it sounded a good deal like Zen and also reminded me quite a bit of the workshop that I mentioned earlier in this thread (here and here, for instance). Well, small world! I came across an interview where Hayes mentioned that years ago, he had in fact been in one of those workshops himself.

More recently, I discovered that Hayes and Linehan had edited a book together, Mindfulness and Acceptance: Expanding the Cognitive-Behavioral Tradition; there's a review of it here. For better or worse, it's geared more to psychologists and such than to the general public. From one of the Amazon reviews:

this will be a very useful book to folks who are interested in how concepts of acceptance and mindfulness can be integrated with, or change for the better, cognitive behavioral treatments. if you have no idea what the previous sentence means, then you are probably not one of those folks!
