There's a certain slant of light...

1       There's a certain slant of light,
2       On winter afternoons,
3       That oppresses, like the weight
4       Of cathedral tunes.

5       Heavenly hurt it gives us;
6       We can find no scar,
7       But internal difference
8       Where the meanings are.

9       None may teach it anything,
10     'Tis the seal, despair,--
11     An imperial affliction
12     Sent us of the air.

13     When it comes, the landscape listens,
14     Shadows hold their breath;
15     When it goes, 'tis like the distance
16     On the look of death.
