William Butler Yeats - Anima Hominis (Chap.11) lyrics

Many years ago I saw, between sleeping and waking, a woman of incredible beauty shooting an arrow into the sky, and from the moment when I made my first guess at her meaning I have thought much of the difference between the winding movement of nature and the straight line, which is called in Balzac's Seraphita the “Mark of Man,” but comes closer to my meaning as the mark of saint or sage. I think that we who are poets and artists, not being permitted to shoot beyond the tangible, must go from desire to weariness and so to desire again, and live but for the moment when vision comes to our weariness like terrible lightning, in the humility of the brutes. I do not doubt those heaving circles, those winding arcs, whether in one man's life or in that of an age, are mathematical, and that some in the world, or beyond the world, have foreknown the event and pricked upon the calendar the life-span of a Christ, a Buddha, a Napoleon: that every movement, in feeling or in thought, prepares in the dark by its own increasing clarity and confidence its own executioner. We seek reality with the slow toil of our weakness and are smitten from the boundless and the unforeseen. Only when we are saint or sage, and renounce Experience itself, can we, in the language of the Christian Caballa, leave the sudden lightning and the path of the serpent and become the bowman who aims his arrow at the centre of the sun.
