LOVE ALL AT ONCE

Love all at once – heart bursting into head,
Every not yet and now and vanished instant - :
Would crack the brain, like as if all the dead,
Those who will be and those who are at present,
Sucked, great star-cloud, into a garden shed,
Or every rose-seed crammed into one case,
Growing one rose, with the whole world, its bed,
Squeezed in the talon roots. The human race,
Its final number, has to be outspread,
Like refugees on a long road, flung dots
Of difference, fields not murdered into bread,
And roses have to grow in separate spots;
And I have got to love you bit by bit: -
Flashes of scraps, like windows headlight-lit.
