There's a certain Slant of light
 

There's a certain Slant of light,
  Winter Afternoons--
  That opresses, like the Heft
  Of Cathedral Tunes--

  Heavenly Hurt, it gives us--
  We can find no scar,
  But internal difference,
  Where the meanings are--

  None may teach it--Any--
  'Tis the Seal Despair--
  An imperial affliction
  Sent us of the Air--

  When it comes, the Landscape listens--
  Shadows--hold their breath--
  When it goes, 'tis like the Distance
  On the look of Death--

-- Emily Dickinson
