Crazy Jane And Jack The Journeyman

I know, although when looks meet
I tremble to the bone,
The more I leave the door unlatched
The sooner love is gone,
For love is but a skein unwound
Between the dark and dawn.

A lonely ghost the ghost is
That to God shall come;
I - love's skein upon the ground,
My body in the tomb -
Shall leap into the light lost
In my mother's womb.

But were I left to lie alone
In an empty bed,
The skein so bound us ghost to ghost
When he turned his head
passing on the road that night,
Mine must walk when dead.

-- William Butler Yeats, The Winding Stair and Other Poems, 1933
