“This is very trying for you, dear child! But I must get on with my task, and when I have done, it’s my belief you’ll forget the pain for joy. In the first place, you are not a very wicked girl because these ugly thoughts master you; I don’t say, mind you, that you will be without offence once you get the key between your fingers; but as it is, you need not sit in judgment on yourself any more.”

Then Dr. Evans went on to make clear to Dorothy what he had already made clear to us of the interaction of thought and brain; how that Thought, Brain, & Co., were such close allies that nobody could tell which of the two did what: that they even ran a business of their own, independently of Ego, who was supposed to be the active head of the firm, and so on.

Dorothy listened with absorbed intentness, as if every word were saving; but the light of hope died slowly out.

“I think I see what you mean; these black thoughts come and rampage even against the desire of the Ego, I, myself: but, oh doctor, don’t you see, that’s all the worse for me?”

“Stop a bit, stop a bit, my dear young lady, I have not done yet. Ego sees things are going wrong and asserts himself; sets up new thoughts in a new course, and stops the old traffic, and in course of time, and a very short time too, the old nerve connections are broken, and the old way under tillage; no more opening for traffic there. Have you got it?”

“I think so. I’m to think of something else, and soon there will be no room in the brain for the ugly thoughts which distress me. But that’s just the thing I can’t do!”

“But that is exactly the only thing you have power to do! Have you any idea what the will is, and what are its functions?”

“I don’t know much about it. I suppose your will should make you able to do the right thing when you feel you can’t! You should say, I will, and go and do it. But you don’t know how weak I am. It makes no difference to me to say, I will!”

“Well, now, to own up honestly, I don’t think it ever made much difference to anybody outside of the story-books. All the same, Will is a mighty fellow in his own way, but he goes with a sling and a stone, and not with the sword of Goliath. He attacks the giant with what seems a child’s plaything, and the giant is slain. This is how it works. When ill thoughts begin to molest you, turn away your mind with a vigorous turn, and think of something else. I don’t mean think good forgiving thoughts, perhaps you are not ready for that yet; but think of something interesting and pleasant; the new dress you must plan, the friend you like best, the book you are reading; best of all, fill heart and mind suddenly with some capital plan for giving pleasure to some poor body whose days are dull. The more exciting the thing you think of, the safer you are. Never mind about fighting the evil thought. This is the one thing you have to do; for this is, perhaps, the sole power the will has. It enables you to change your thoughts; to turn yourself round from gloomy thoughts to cheerful ones. Then you will find that your prayers will be answered, for you will know what to ask for, and will not turn your back on the answer when it comes. There, child, I have told you the best secret of an old man’s life, and have put into your hands the key of self-government and a happy life. Now you know how to be better than he that taketh a city.”

“Thank you a thousand times for your precious secret. You have lifted my feet out of the slough. I will change my thoughts (may I say that?). You shall find that your key does not rust for want of use. I trust I may be helped from above never to enter that cloud again.”
