“Evil has always been symbolized by darkness, and Good by light, and hidden within the symbol is contained the perfect interpretation, the reality; for, just as light always floods the universe, and darkness is only a mere speck or shadow cast by a small body intercepting a few rays of the illimitable light, so the Light of the Supreme Good is the positive and life-giving power which floods the universe, and evil the insignificant shadow cast by the self that intercepts and shuts off the illuminating rays which strive for entrance. When night folds the world in its black impenetrable mantle, no matter how dense the darkness, it covers but the small space of half our little planet, while the whole universe is ablaze with living light, and every soul knows that it will awake in the light in the morning. Know, then, that when the dark night of sorrow, pain, or misfortune settles down upon your soul, and you stumble along with weary and uncertain steps, that you are merely intercepting your own personal desires between yourself and the boundless light of joy and bliss, and the dark shadow that covers you is cast by none and nothing but yourself. And just as the darkness without is but a negative shadow, an unreality which comes from nowhere, goes to nowhere, and has no abiding dwelling-place, so the darkness within is equally a negative shadow passing over the evolving and Light-born soul.
‘But,’ I fancy I hear someone say, ‘why pass through the darkness of evil at all?’ Because, by ignorance, you have chosen to do so, and because, by doing so, you may understand both good and evil, and may the more appreciate the light by having passed through the darkness. As evil is the direct outcome of ignorance, so, when the lessons of evil are fully learned, ignorance passes away, and wisdom takes its place. But as a disobedient child refuses to learn its lessons at school, so it is possible to refuse to learn the lessons of experience, and thus to remain in continual darkness, and to suffer continually recurring punishments in the form of disease, disappointment, and sorrow. He, therefore, who would shake himself free of the evil which encompasses him, must be willing and ready to learn, and must be prepared to undergo that disciplinary process without which no grain of wisdom or abiding happiness and peace can be secured.
A man may shut himself up in a dark room, and deny that the light exists, but it is everywhere without, and darkness exists only in his own little room. So you may shut out the light of Truth, or you may begin to pull down the walls of prejudice, self-seeking and error which you have built around yourself, and so let in the glorious and omnipresent Light. By earnest self-examination strive to realize, and not merely hold as a theory, that evil is a passing phase, a self-created shadow; that all your pains, sorrows and misfortunes have come to you by a process of undeviating and absolutely perfect law; have come to you because you deserve and require them, and that by first enduring, and then understanding them, you may be made stronger, wiser, nobler. When you have fully entered into this realization, you will be in a position to mold your own circumstances, to transmute all evil into good and to weave, with a master hand, the fabric of your destiny.”
James Allen is one of those New Thought authors that sometimes gets dismissed for being a little too cute or a little too simple. But paragraphs like this, from chapter one of From Poverty to Power ring with truth, and a deep spiritual understanding. There is no darkness in the universe, no evil – nothing to make us suffer except ourselves, and the shadow we cast through misuse of the faculty of thought.
