I have always been attracted by the veil, by seeing through a glass, darkly:
And the children in the apple-tree
Not known, because not looked for
But heard, half heard, in the stillness
Between the two waves of the sea
- from Little Gidding, T.S. Eliot
When I was a child I caught a fleeting glimpse,
Out of the corner of my eye.
I turned to look but it was gone.
I cannot put my finger on it now
