It is at those moments when we are, as we say, in a bad mood, when we feel incapable of the elevation of soul that befits holy things, it is then that it is most effectual to turn our eyes toward perfect purity. For it is then that evil, or other mediocrity, comes to the surface of the soul and is in the best position for being burned by contact with fire.
–Simone Weil, Waiting for God
