When people begin to realize what suggestion means, many react wrongly against it. For instance they think that to say to oneself, "I am well," is suggestion, and they wonder whether it is not wrong. But they do not know that from morning till evening we are impressed by suggestions coming to us automatically in different forms. The importance does not lie in receiving suggestions or in rejecting suggestions; it lies in understanding what will benefit us and what will be detrimental. Suggestions about haunted houses make people afraid or ill; because of such a suggestion they believe that the house is haunted, and that in itself is enough to make them feel ill.
