Achilles, Man at War With Himself

Rage–Goddess, sing the rage of Peleus’ son AchillesMurderous, doomed, that cost the Achaeans countless losses,hurling down to the House of Death so many sturdy souls,great fighters’ souls, but made their bodies carrion,feasts for the dogs and birds,and the will of Zeus was moving toward its end. Begin, Muse, when the two first broke and clashed.

The rage of Achilles is an internal conflict–man at war with himself. Quite apart from the breath of the eternal Atman.
