Specifically engineered bio-rhythmic music with embedded subliminals, designed specifically to help aid in pain management. Meditate, relax, enter self-hypnosis, or just listen to the calming, ethereal music in the background. Ideal with stereo headphones to take full advantage of the binaural engineering, but also effective without them. This is what I use when undergoing a potentially painful procedure, and even simply to relax sometimes. Perfect to accompany practice of self-hypnosis.
