When a man enters a dark room he is not sure of his movements, he cannot see objects around him, or properly locate them, and is liable to hurt himself by coming into sudden contact with them. But let a light be introduced, and immediately all confusion disappears. Every object is seen, and there is no danger of being hurt. To the majority, life is such a dark room, and their frequent hurts—their disappointments, perplexities, sorrows and pains—are caused by sudden contact with principles which they do not see, and are therefore not prepared to deal with. But when the light of wisdom is introduced into the darkened understanding, confusion vanishes, difficulties are dissolved, all things are seen in their true place and proportion, and henceforth the man walks open-eyed and unhurt, in the clear light of wise comprehension. - Summary by James Allen
