XXXI. (From Book III. Nature)

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

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

None may teach it anything,
' T is the seal, despair,—
An imperial affliction
Sent us of the air.

When it comes, the landscape listens,
Shadows hold their breath;
When it goes, 't is like the distance
On the look of death.

--Emily Dickinson
