Most blocked creatives are cerebral beings. We think of all the things we want to do, but can't. Early in recovery, we next think of all the things we want to do but don't. In order to effect a real recovery, one that lasts, we need to move out of the head and into a body of work. To do this, we must first of all move into the body.
Again, this is a matter that requires acceptance. Creativity requires action, and part of that action must be physical. It is one of the pitfalls of Westerners adopting Eastern meditation techniques to bliss out and render ourselves high but dysfunctional. We lose our grounding, and with it, our capacity to act in the world. In pursuit of higher consciousness, we render ourselves unconscious in a new way.
Exercise combats this spiritually-induced dysfunction.
