The most powerful weapon on the planet is hidden right behind your eyes.

Your mind is capable of things you've hardly dared to dream about: controlling others and travelling through time and space.

Amazing facts from Herbie Brennan's "Strange Powers of the Human Mind" are: the brain has no pain receptors - that's why a surgeon can slice into it without you feeling a thing; Buddhists believe that the entire universe is maya, an illusion generated by the human mind; a quarter of all British students have had an out-of-body experience; there is evidence that hypnosis was used in Ancient Egypt, Ancient China and Ancient Greece - it was sometimes called 'temple sleep' or mekhenesis, which means 'the taking away of responsibility'.
