Limitations - Poem by Siegfried Sassoon

If you could crowd them into forty lines!
Yes; you can do it, once you get a start;
All that you want is waiting in your head,
For long-ago you’ve learnt it off by heart.

. . . .
Begin: your mind’s the room where you have slept,
(Don’t pause for rhymes), till twilight woke you early.
The window stands wide-open, as it stood
When tree-tops loomed enchanted for a child
Hearing the dawn’s first thrushes through the wood
Warbling (you know the words) serene and wild.

You’ve said it all before: you dreamed of Death,
A dim Apollo in the bird-voiced breeze
That drifts across the morning veiled with showers,
While golden weather shines among dark trees.

You’ve got your limitations; let them sing,
And all your life will waken with a cry:
Why should you halt when rapture’s on the wing
And you’ve no limit but the cloud-flocked sky?...

But some chap shouts, ‘Here, stop it; that’s been done!’—
As God might holloa to the rising sun,
And then relent, because the glorying rays
Remind Him of green-glinting Eden days,
And Adam’s trustful eyes as he looks up
From carving eagles on his beechwood cup.

Young Adam knew his job; he could condense
Life to an eagle from the unknown immense....
Go on, whoever you are; your lines can be
A whisper in the music from the weirs
Of song that plunge and tumble toward the sea
That is the uncharted mercy of our tears.

. . . .
I told you it was easy! ... Words are fools
Who follow blindly, once they get a lead.
But thoughts are kingfishers that haunt the pools
Of quiet; seldom-seen: and all you need
Is just that flash of joy above your dream.
So, when those forty platitudes are done,
You’ll hear a bird-note calling from the stream
That wandered through your childhood; and the sun
Will strike the old flaming wonder from the waters....
And there’ll be forty lines not yet begun.
