Supposing for some cause you really are ill, why then help this evil state to augment by your thoughts? Rather impede its progress as far as you can by creating good-thought conditions. You may reply, "But I am constantly doing this, and yet nothing good comes." Pause and use your common sense by remembering that for twenty--thirty--forty years perhaps, when you did not analyse matters, you were laying up for yourself numberless stumbling-blocks by wrong thinking, which according to the law we are discussing must be surmounted before you can start on a clear road. And the reason why you do not immediately receive the result of your good thoughts is that you are still under the action of your bad ones. But if you recognise this law of the power of thought, you need not incur for yourself any further debts to pay. And to recognise it as a law you have only to use your common sense to see that it is not conceivable that thoughts can have no effect outside your own brain. They cannot be wasted and go into nothingness, they _must_ strike some answering vibration somewhere, and it is surely rational to suppose they will strike the kindred vibration rather than some totally different one, as the Marconi messages strike the pole in tune to them. At least, it is worth while trying to believe this, because if you can it will make you happier. Alas! I am not a scientist who can dogmatically prove every fraction of my beliefs. I only want to awaken my readers to think for themselves upon this interesting subject, for the facts are there for us all to investigate, unaided by scientists, if we will. So without any more argument, shall we take it for granted that you are with me thus far, and have seen my point? Yes. Then let us examine what our thoughts do for us. For example, let us suppose a man has a disease which is believed to be incurable. His thoughts tell him so constantly, and the thoughts of his friends, often expressed in words, convince him still further of his misfortune. He is certain nothing he can do will make it better, and any remedy that is applied will only meet with failure. He has made his mental picture of an incurable disease; and so he is helping the material result to accomplish itself. But, as hope springs eternal in the human breast, he still goes from doctor to doctor for fresh advice, while unconsciously nullifying the benefit he might receive from doing so by his attitude of mind in holding the belief that nothing can cure him. We must all of us know of cases like this, and have seen the gradual increase in the person's illness.
