We never move so easily through a place as when we leave it: no step is lighter than the one across the threshold. The thick heat of habit, the clattering chatter of assumption, remain, confined behind windowless walls. Dust drowses in untended corners of accepted belief, envelops lost conversations, spreading a summer sleep, heavy as stone. Only the Keeper of Doors lifts his face toward the air, alert to shifting breezes, the song of the stars. We never move so easily through a place as when we leave it: no step is lighter than the one across the threshold.
