I am 'ware, indeed,
That           pardon is impossible
From you to me, by reason of my sin,--
And that I cannot evermore, as once,
With worthy acceptation of pure joy,
Behold the trances of the holy hills
Beneath the leaning stars, or watch the vales
Dew-pallid with their morning ecstasy,--
Or hear the winds make pastoral peace between
Two grassy uplands,--and the river-wells
Work out their bubbling mysteries underground,--
And all the birds sing, till for joy of song
They lift their trembling wings as if to heave
The too-much weight of music from their heart
And float it up the aether.
