My background is in yoga and meditation, and I have always been taught that the best route for one to take when ill (or any time, for that matter), is to completely accept what your circumstances are, breathe into the pain, and watch it change. By accepting the now, and not letting the mind drift into the past or future, peace can eventually be attained because you are not resisting. In Christian Science, which I am new to, I find I'm fighting and resisting constantly in trying to deny my physical pain. How can one find peace in that?
I, too, have had training in yoga. It has taught me to be still, to cultivate my concentration, to perceive my inner balance. This focus gives one a sense of control, or dominion, over the body. However, the best concept of dominion is not simply in the mastery of the body, but, more important, in the mastery of a mentality that says you are subordinate to your body.
I recently cut my finger. When I thought about how the sensation of pain could not be due to a physical circumstance that happened to my finger, but rather the simple notion that something was out of harmony at that moment, I could begin to dissociate the pain from my finger. The pain gradually reduced. By the next day, my finger had completely healed except for a small dot.
