In the life of every man there are sudden transitions of feeling, which seem almost miraculous. At once, as if some magician had touched the heavens and the earth, the dark clouds melt into the air, the wind falls, and serenity succeeds the storm. The causes which produce these changes may have been long at work within us, but the changes themselves are instantaneous, and apparently without sufficient cause.
Henry Wadsworth LongfellowOut of the bosom of the Air, Out of the cloud-folds of her garments shaken, Over the woodlands brown and bare, Over the harvest-fields forsaken, Silent, and soft, and slow Descends the snow.
Henry Wadsworth Longfellow
