Stretch because it feels goooood, never for pain reduction, but because you enjoy the experience and want to feel flexible. Lift, run, exercise for health, tension reduction, and a sense of wellbeing--never for pain reduction. In fact, never do anything for pain reduction, or you're TMSing. Your brain would love for you to do things for pain reduction, so that your 'problem' can be swept inside.
Never let symptoms stop you from doing anything (unless you're dizzy and about to perform brain surgery and/or self-vasectomy). The idea is not to heal, never try to heal. The idea is to take away the need for the obsession. Since fear is at that beginning of the chain of TMS events, start there. It's not just a fear of death, but it's also a fear of shame and guilt, for being exposed for who you really are.
Like Dr. Sarno said, he didn't have a method for treating pain. He had a method for dealing with the reason for the pain. The same is true for all obsessions, like pain. Why do you need to worry about pain, and body? Or phobias or anything? That's the mechanism to get to. If you have deep fear, then when you heal from TMS, your need for an obsession will simply shift to something else, like drinking, phobia-ing, dancing, singing, etc...anyth-ing.
As long as you care about your body, or what your body is doing, you are still TMSing. In my experience, the most common form of TMSing that I see is people asking questions about whether they can do this or that, etc. The new TMS-obsession is on "healing perfectly." They don't realize that their new obsessive focus is slowly shifting from body-obsession to question-obsession.
They can never be free until they become aware that thinking is replacing feeling, and therefore, living. I quoted Emile Chartier in GPD, "To think, is to say no." Did anyone understand why? The real conflict is not within the mind, but between the head and the heart.
Go live in the moment, doing what you love with all your heart, then you are free. If you love it, your fear fades. Hate is not the opposite of love, fear is.
