Work is any activity, or non-activity, that gets you out of mind and into energy. If this use of the word energy confuses or alienates then simply reword: out of thinking (worrying) and into the imagination. Any artist (or child) knows that the imagination does not belong to them. It is, they know, an intersection of their own ethereal being with reality at large, and only when they have the courage to leave the stifling safety of the known and gaze awestruck into the unknown do the images come alive. And this is heart, always forward, even over the precipice, whereas mind ever retreats into its own interpretations.
