Walt Whitman

Leaves of Grass. 5. Calamus. 38. 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 among my lovers and caroling these songs,
O I never doubt whether that is really me.
