The Monroe Institute
is a consciousness expanding center that utilizes RF and other sound acoustics / brain development tools in order to help people get out of their bodies and basically have an out-of-the- body travel experience. The founder is Bob Monroe and his goal was to help others experienced what he had discovered on the inner planes ... to spiritually mature.
Bob Monroe was a multimillionaire who had made his wealth in Radio and Broadcasting. He started a lab to investigate the effects on the brain and consciousness in 1956-1958. At some point he had an OBE. He dedicated the rest of his life to developing protocols and teaching methods to help others achieve their own OBE, so as to experience reality for one self, first hand.
Hemi-Sync is a trademarked brand name for a patented process used to create audio patterns in the form of audio CDs.
Hemi-Sync is short for Hemispheric Synchronization, also known as brainwave synchronization. Monroe indicated that the technique synchronizes the two hemispheres of one's brain, thereby creating a 'frequency-following response' designed to evoke certain effects. Hemi-Sync has been used for many purposes, including relaxation and sleep induction, learning and memory aids, helping those with physical and mental difficulties, and reaching altered states of consciousness through the use of sound.
The technique involves using sound waves to entrain brain waves. Wearing headphones, Monroe claimed that brains respond by producing a third sound (called binaural beats) that encouraged various brainwave activity changes. In 2002, a University of Virginia presentation at the Society for Psychophysiologial Research examined Monroe's claim. The presentation demonstrated that EEG changes did not occur when the standard electromagnetic headphones of Monroe's setup were replaced by air conduction headphones that were connected to a remote transducer by rubber tubes. This suggests that the basis for the entrainment effects is electromagnetic rather than acoustical.
Replicated, double-blind, randomized trials on anesthetized patients have found Hemi-Sync effective as a partial replacement for fentanyl during surgery. A similar study found it ineffective at replacing propofolhowever.
In a nut shell Bob discovered that certain frequencies open up the "Gate" ("Gateway") to experiencing the out of body state. I like Bob Monroe's approach because like Indian Meditation he uses "sounds" (liken Mantras) and breathing and visualization to produce the needed sound wave resonance in the brain which will support a spontaneous trip outside the body. You maintain full control, not the drug.
