Robert Anton Wilson often talked and wrote positively about his personal experience with light and sound machines and NLP. This new AVE (Audio Visual Entrainment) device comes with the L.E.D glasses, a small machine and a library of around 500 hypnotic recordings. You can even store 5 sessions on your smart phone. Nearly 50 of these are by Dr. Richard Bandler. I've found it to be extremely useful as I'm sure you will too.
