Mellas was transported outside himself, beyond himself.....

“ Mellas was transported outside himself, beyond himself. It was as if his mind watched eveything coolly while his body raced wildly with passion and fear. He was frightened beyond any fear he had ever known. But this brilliant and intense fear, this terrible here and now, combined with the crucial significance of every movement of his body, pushed him over a barrier whose existence he had not known about until this moment. He gave himself over completely to the god of war within him. ”
