The author is the founder of Centerpointe Research Institute. He demonstrates how Holosync audio technology ends emotional dysfunction, improves mental functioning, and creates profound and lasting happiness. I listen to the audio chimes and they place me in a deep meditative state with very little effort on my part. It's great.
