Saturday's Poem

I just started reading The Stream & the Sapphire, a book of poetry by Denise Levertov. She took poems from seven different volumes of her poetry, and collected them in this book as a way of chronicling her own journey from agnosticism to Christianity, "a movement incorporating much of doubt and questioning as well as of affirmation" (vii).

Her are some verses from "Flickering Mind" (15-16).

Lord, not you,
it is I who am absent.
At first
belief was a joy I kept in secret,
stealing alone
into sacred places:
a quick glance and away--and back,
circling.
I have long since uttered your name
but now
I elude your presence....
...Not you,
it is I am absent.
You are the stream, the fish, the light,
the pulsing shadow,
you the unchanging presence, in whom all
moves and changes.
How can I focus my flickering, perceive
at the fountain's heart
the sapphire I know is there?
