How insupportable would be the days,

if the night with its dews and darkness

did not come to restore the drooping world.

—HENRY DAVID THOREAU

To go in the dark with a light is to know the light.

To know the dark, go dark. Go without sight,

and find that the dark, too, blooms and sings,

and is traveled by dark feet and dark wings.

—WENDELL BERRY
