John of the Cross - The Fountain

How well I know that flowing spring
     in black of night.

The eternal fountain is unseen.
How well I know where she has been
     in black of night.

I do not know her origin.
None. Yet in her all things begin
     in black of night.

I know that nothing is so fair
and earth and firmament drink there
     in black of night.

I know that none can wade inside
to find her bright bottomless tide
     in black of night.

Her shining never has a blur;
I know that all light comes from her
     in black of night.

I know her streams converge and swell
and nourish people, skies and hell
     in black of night.

The stream whose birth is in this source
I know has a gigantic force
     in black of night.

The stream from but these two proceeds
yet neither one, I know, precedes
     in black of night.

The eternal fountain is unseen
in living bread that gives us being
     in black of night.

She calls on all mankind to start
to drink her water, though in dark,
     for black is night.

O living fountain that I crave,
in bread of life I see her flame
     in black of night.
