In the 1970s, binaural beats were used for therapeutic purposes. Robert Monroe, the founder of the Monroe Institute, pioneered using binaural beats for relaxation, meditation, and altered states of consciousness. Monroe developed a technology called "Hemi-Sync," which used binaural beats to synchronize the left and right hemispheres of the brain and induce various mental states.

The 1970s and the strange experiments happening at that time regarding human consciousness and altered states are fascinating. The show Stranger Things is based on the MK-Ultra experiments conducted by the United States. However, explaining what that was is a whole other episode and a different podcast. Here's something interesting, though, have you ever heard of the gateway process? The Gateway Process is a meditation program developed by the Monroe Institute in the 1970s. It is intended to help individuals explore altered states of consciousness and expand their awareness.
