I mentionned in class that I was listening to the Ideas program on CBC radio when they were interviewing Jon Kabat-Zinn. This guy had some really interesting things to say on meditation and spiritual growth (although he'd mock the use of the word spiritual).
So I went to the CBC's website and placed an order for that interview to be delivered to me on CD (I also bought the Steve the First radio play, but that was for my own amusement). Once I've had a chance to listen to it, I'll see about putting it out to the CMS students to have a listen to it.
You can listen to Jon Kabat-Zinn as he gives a talk on the benefits of medicine, meditation, and mindfulness at the ResearchChannel website.
