No More Learning

Imagination, loudening with the surf
Of the midsummer wind among the boughs,
Gathers my spirit from the haunts remote
Of faintest silence and the shades of sleep,
To bear me on the summit of her wave
Beyond known shores, beyond the mortal edge
Of thought terrestrial, to hold me poised
Above the frontiers of infinity,
To which in the full reflux of the wave
Come soon I must, bubble of solving foam,
Borne to those other shores--now never mine
Save for a hovering instant, short as this
Which now sustains me ere I be drawn back--
To learn again, and wholly learn, I trust,
How           it is to wake at night.
