Even without watching the scenery, a walk across hills and glens is a form of meditation in which meter fails and unforced thoughts wander in natural rhythms.

Most sweet it is with unuplifted eyes

— by William Wordsworth

Most sweet it is with unuplifted eyes To pace the ground, if path be there or none, While a fair region round the traveler lies Which he forbears again to look upon; Pleased rather with some soft ideal scene, The work of Fancy, or some happy tone Of meditation, slipping in between The beauty coming and the beauty gone. If Thought and Love desert us, from that day Let us break off all commerce with the Muse: With Thought and Love companions of our way, Whate’er the senses take or may refuse, The Mind’s internal heaven shall shed her dews Of inspiration on the humblest lay.
