Yes. Do The Work on any subject that is stressful. As you become familiar with the four questions and turnarounds, you may choose objects such as the body, disease, career, or even God. Then simply use the term “my thinking” in place of the object when you do the turnarounds.
Example: “My body should be strong, healthy, and flexible" becomes "My thinking should be strong, healthy, and flexible.”
Isn't that what you really want? A balanced, healthy mind? Has a sick body ever been a problem, or is it your thinking about the body that causes the problem? Investigate. Let your doctor take care of your body as you take care of your thinking. I have a friend who can't move his body, and he is loving life. Freedom does not require a healthy body. Free your mind.
