I am a huge fan of audiobooks so I found listening to Dr. Sarno (and other TMS-related books) extremely helpful. However, they were supplements most of the time as I also needed the physical book(s) so I could control the pace, read short sections (and flip thru the book), and stop to reflect.
Be careful because the work is so personal and what works for someone else may come across very different for you. There's also the possibility of expectations getting in the way: 'This is supposed to work so why isn't it resonating with me?'
