Considering my experience with hypnosis, I found this article on meditation pretty exciting.

"Meditation is being recommended by more and more physicians as a way to prevent, slow or at least control the pain of chronic diseases like heart conditions, AIDS, cancer and infertility. It is also being used to restore balance in the face of such psychiatric disturbances as depression, hyperactivity and attention-deficit disorder (ADD). In a confluence of Eastern mysticism and Western science, doctors are embracing meditation not because they think it's hip or cool but because scientific studies are beginning to show that it works, particularly for stress-related conditions."
