Emily Dickinson, "There's a certain Slant of light"

There's a certain Slant of light,
Winter Afternoons --
That oppresses, like the Heft
4
Of Cathedral Tunes --
Heavenly Hurt, it gives us --
We can find no scar,
But internal difference,
8
Where the Meanings, are --
None may teach it -- Any --
'Tis the Seal Despair --
An imperial affliction
12
Sent us of the Air --
When it comes, the Landscape listens --
Shadows -- hold their breath --
When it goes, 'tis like the Distance
16
On the look of Death --
