River

(Found here)

Dreaming the sea that
                                          lies beyond me
I have enough depth
                                       to know I am shallow.

I have my pools, my bowls
                                                 of rock I flow
into and fill, but I must
                                           brim my own banks, persist,
vanish at last in greater flood
                                                     yet still within it
follow my task,
                             dreaming towards
the calling sea.
