Is there anything of value in Theosophical ideas, shall I say to the science of medicine? Some say it is not yet a science, but works empirically only. There is some truth in that; but are there not here again lines of investigation which the physician might well study? For instance, the power of thought over the human body, all that mass of facts on which partly is built up such a science as Mental Healing, or what is called Faith Cure, and so on. Do you think that these things have been going on for hundreds of years, and that there is no truth lying behind them? "The effects of imagination," you say. But what is imagination? It does not matter of what it is the effect, if it brings cure where before there was disease. If you put into a man's body a drug that you do not understand, and find that it cures a disease and relieves a pain, will you throw the drug aside because you do not understand it? And why do you throw the power of imagination aside because you cannot weigh it in your balance, nor find that it depresses one scale more than the other? Imagination is one of the subtlest powers of thought: imagination is one of the strongest powers that the doctor might utilise when his drugs fail him and his old methods no longer serve his purpose. Suggestion, the power of thought. Why, there are records of cases where suggestion has killed! That which has killed can also cure, and man's body being only a product of thought, built up through the ages, answers more rapidly to its creator than it does to clumsier products from the mineral and vegetable kingdoms. Here again I only ask experiment. You know that you can produce wounds upon the body of the hypnotised patient, in a state of trance. By suggestion lesions are made, burns are caused, inflammation and pain appear by the mere suggestion of a wound. A blister is placed on a patient and forbidden to act; the skin is untouched when the blister is removed: a bit of wet paper is given by thought the qualities of the blister, and it will raise the skin, with all the accompaniments of the chemical blister. Now these things are known. You can see the pictures of wounds thus produced, if you will, in some of the Paris hospitals, for along this line the Frenchman is investigating further than the Englishman has done. And along that line also lies much of useful experiment to be brought to the relief of the diseases of humanity.
