We all experience many states of consciousness, from ordinary waking and sleeping to extraordinary states in which we are more at peace, particularly aware, or exceptionally creative. Each of these states is associated with a particular pattern of brainwave activity. Dr. Jeffrey Thompson has been experimenting with sound and brainwaves scientifically since 1980, developing innovative techiques for embedding brainwave audio pulses into musical soundtracks. After a few minutes of listening, your own brainwaves naturally "lock" onto the inaudible pulses, and lead you easily into the state of mind you choose.
