In my doc. seminar, we had been discussing Moffett's essay called "Inner Speech." We had discussed how sometimes people have a weird reaction to the idea of meditation in the classroom. I accidentally came across the blog. I had not heard the story on NPR. Here is his blog. http://tackingtowardtranscendence.blogspot.com/2005/10/misguided-angels.html
I tried a writing exercise in Elbow and Belanoff's A Community of Writer's. After reading Moffett's piece, I would say that it is meditation. What a great way to tap into your inner speech. A few minutes of quiet before writing can make a huge difference in our writing.
