The Secret (a poem by Denise Levertov)

The Secret
by Denise Levertov
Two girls discover the secret of life in a sudden line of poetry. I who don't know the secret wrote the line. They told me (through a third person) they had found it but not what it was not even what line it was. No doubt by now, more than a week later, they have forgotten the secret, the line, the name of the poem. I love them for finding what I can't find, and for loving me for the line I wrote, and for forgetting it so that a thousand times, till death finds them, they may discover it again, in other lines in other happenings. And for wanting to know it, for assuming there is such a secret, yes, for that most of all.
