Telepathy, or mind-reading: that is to say, can one human mind communicate with another human mind, except by the sense channels ordinarily known and used—seeing, hearing, feeling, tasting and touching? Can a thought or image in one mind be sent directly to another mind and there reproduced and recognized? If this can be done, how is it done? Is it some kind of vibration, going out from the brain, like radio broadcasting? Or is it some contact with a deeper level of mind, as bubbles on a stream have contact with the water of the stream? And if this power exists, can it be developed and used? Is it something that manifests itself now and then, like a lightning flash, over which we have no control? Or can we make the energy and store it, and use it regularly, as we have learned to do with the lightning which Franklin brought from the clouds?
These are the questions; and the answers, as well as I can summarize them, are as follows: Telepathy is real; it does happen. Whatever may be the nature of the force, it has nothing to do with distance, for it works exactly as well over forty miles as over a few feet. And while it may be spontaneous and may depend upon a special endowment, it can be cultivated and used deliberately, as any other object of study, in physics and chemistry. The essential in this training is an art of mental concentration and auto-suggestion, which can be learned. I am going to tell you not merely what you can do, but how you can do it, so that if you have patience and real interest, you can make your own contribution to knowledge.
