hemisync tapes

Back in the 80's before getting Steven Gibbs HDR, I used hemisync tapes for meditation music. The principle of the hemisync is easy. Let's say in your right ear is an, 86 Hertz sound and in your left ear is an 80 Hertz sound. What this does is create a carrier wave of six cycles per second. This will entrain your brain to the six cycle theta state. The theta brain wave state is related to meditation and used by technoshamans to attain a relaxed higher state of consciousness.
