Earth! my Likeness!

EARTH! my likeness!
Though you look so impassive, ample and spheric there,
I now suspect that is not all;
I now suspect there is something fierce in you, eligible to burst
  forth;
For an athlete is enamour'd of me-and I of him;
But toward him there is something fierce and terrible in me, eligible
  to burst forth,
I dare not tell it in words-not even in these songs.
