Analysis of That Shadow, My Likeness

   THAT shadow, my likeness, that goes to and fro, seeking a livelihood,
         chattering, chaffering;
   How often I find myself standing and looking at it where it flits;
   How often I question and doubt whether that is really me;
   --But in these, and among my lovers, and caroling my songs,
   O I never doubt whether that is really me.
