Homeward bound I suddenly noticed before me my own shadow as I had seen the shadow of the other war behind the actual one. During all this time it has never budged from me, that irremovable shadow, it hovers over every thought of mine by day and by night; perhaps its dark outline lies on some pages of this book, too. But, after all, shadows themselves are born of light. And only he who has experienced dawn and dusk, war and peace, ascent and decline, only he has truly lived.
