Now that you lie
In London afar,
And may sleep longer
Though lonelier,
For I shall not wake you
With a nightmare,
Heaven plant such peace in us
As if no parting stretched between us.

The world revolves
And is evil;
God's image is
Wormeaten by the devil;
May the good angel
Have no rival
By our beds, and we lie curled
At the sound unmoving centre of the world.

In our good nights
When we were together,
We made, in that stillness
Where we loved each other,
A new being, of both
Yet above either:
So, when I cannot share your sleep,
Into this being, half yours, I creep.
