Further, you will observe more and more clearly, that the stuff of your external world, the method and machinery of the common life, is not merely passively but actively inconsistent with your sharp interior vision of truth. The heavy animal is diseased as well as indolent. All man's perverse ways of seeing his universe, all the perverse and hideous acts which have sprung from them-- these have set up reactions, have produced deep disorders in the world of things. Man is free, and holds the keys of hell as well as the keys of heaven. Within the love-driven universe which you have learned to see as a whole, you will therefore find egotism, rebellion, meanness, brutality, squalor: the work of separated selves whose energies are set athwart the stream. But every aspect of life, however falsely imagined, can still be "saved," turned to the purposes of Reality: for "all-thing hath the being by the love of God." Its oppositions are no part of its realness; and therefore they can be overcome. Is there not here, then, abundance of practical work for you to do; work which is the direct outcome of your mystical experience? Are there not here, as the French proverb has it, plenty of cats for you to comb? And isn't it just here, in the new foothold it gives you, the new clear vision and certitude--in its noble, serious, and invulnerable faith-- that mysticism is "useful"; even for the most scientific of social reformers, the most belligerent of politicians, the least sentimental of philanthropists? To "bring Eternity into Time," the "invisible into concrete expression"; to "be to the Eternal Goodness what his own hand is to a man"--these are the plainly expressed desires of all the great mystics. One and all, they demand earnest and deliberate action, the insertion of the purified and ardent will into the world of things. The mystics are artists; and the stuff in which they work is most often human life. They want to heal the disharmony between the actual and the real: and since, in the white-hot radiance of that faith, hope, and charity which burns in them, they discern such a reconciliation to be possible, they are able to work for it with a singleness of purpose and an invincible optimism denied to other men. This was the instinct which drove St. Francis of Assist to the practical experience of that poverty which he recognised as the highest wisdom; St. Catherine of Siena from contemplation to politics; Joan of Arc to the salvation of France; St. Teresa to the formation of an ideal religious family; Fox to the proclaiming of a world-religion in which all men should be guided by the Inner Light; Florence Nightingale to battle with officials, vermin, dirt, and disease in the soldiers' hospitals; Octavia Hill to make in London slums something a little nearer "the shadows of the angels' houses" than that which the practical landlord usually provides.
