"The theory behind binaural beats is that if you apply slightly different frequency sine waves to each ear, a beating affect is created in the brain itself, due to the brain’s internal wiring. If, in the presence of these tones, you relax and let your mind go, your mind will naturally synchronize with the beat frequency. In this way it is possible to tune the frequency of your brain waves to particular frequencies that you have selected, using of the four bands: Delta: deep sleep, Theta: dreaming and intuitive, Alpha: awake, focussed inside, and Beta: awake, focussed outside. It is also possible to produce mixtures of brain waves of different frequencies by mixing binaural tones, and in this way, with practice and experimentation, it is possible to achieve rather unusual states, such as out-of-body experiences."
“A map of the world that does not include Utopia is not worth even glancing at, for it leaves out the one country at which Humanity is always landing. And when Humanity lands there, it looks out, and, seeing a better country, sets sail. Progress is the realisation of Utopias.”—Oscar Wilde, from The Soul of Man Under Socialism
