Many years ago I had a pain that developed for no reason. It was a pain in my index finger almost unbearable. Using my hand to work with my "mouse" was getting almost impossible.
I tried many things but nothing. I then remembered I had Shinzen's cd program which I had not listened to. At the time I had no idea really what mindfulness meditation was either.
I listened to the cds and did it. The first few days nothing much happened with my finger, but something happened deeper. I can not name, but it was shift that, as I now see changed everything. It took about a week for pain to go away and I can say that what did happen is that the pain no longer mattered. This was back in 2003!
Anyway, Shinzen's practices are tried and true. He is a true master meditation teacher.
