W. S. Merwin: "The New Song"

                                  For some time I thought there was time
                                  and that there would always be time
                                  for what I had a mind to do
                                  and what I could imagine
                                  going back to and finding it
                                  as I had found it the first time
                                  but by this time I do not know
                                  what I thought when I thought back then

                                  there is no time yet it grows less
                                  there is the sound of rain at night
                                  arriving unknown in the leaves
                                  once without before or after
                                  then I hear the thrush waking
                                  at daybreak singing the new song
