In his highly insightful work, Inside Job, Stephen W. Smith shares insights on the topic of rest from the poet David Whyte:
[The] poet David Whyte opens our minds and hearts to rest when he writes: Rest is the conversation between what we love to do and how we love to be. Rest is the essence of giving and receiving. Rest is an act of remembering, imaginatively and intellectually but also physiologically and physically.
To rest is to give up on the already exhausted will as the prime motivator of endeavor, with its endless outward need to reward itself through established goals. To rest is to give up on worrying and fretting and the sense that there is something wrong with the world unless we put it right; to rest is to fall back literally or figuratively from outer targets and shift the goal not to an inner bulls eye, an imagined state of perfect stillness, but to an inner state of natural exchange.
