Here you will find the Poem Variation on a Theme by Rilke of poet Denise Levertov
A certain day became a presence to me; there it was, confronting me--a sky, air, light: a being. And before it started to descend from the height of noon, it leaned over and struck my shoulder as if with the flat of a sword, granting me honor and a task. The day's blow rang out, metallic--or it was I, a bell awakened, and what I heard was my whole self saying and singing what it knew: I can.
