to and fro in shadow from inner to outer shadow

      from impenetrable self to impenetrable unself
      by way of neither

      as between two lit refuges whose doors once
      neared gently close, once away turned from
      gently part again

      beckoned back and forth and turned away

      heedless of the way, intent on the one gleam
      or the other

      unheard footfalls only sound

      till at last halt for good, absent for good
      from self and other

      then no sound

      then gently light unfading on that unheeded

      unspeakable home

      Samuel Beckett
