Over the years, I've recommended many simple and natural ways for people to improve their health. And people report back to me that they get more positive results from one technique than any other: the breathwork that I teach on my new audio program.

I feel very strongly that proper breathing is a master key to good health. Over and over again, I'm impressed by the power of the breath and its ability to correct specific health problems and promote our general wellness. People who practice these breathing exercises tell me that they improve circulation and digestion, correct irregular heartbeats, and alleviate panic disorders and other anxiety states.

And not only does breathwork really work, it costs nothing. It requires no equipment, and it's simple to practice. And, of course, it's literally right under our nose.

In the four years I spent at Harvard Medical School, I learned nothing about the healing power of breath. I learned about the anatomy of the respiratory system, and I learned about diseases of the respiratory tract. But I learned nothing about breath as the connection between the conscious and unconscious mind, or the doorway to the control of the autonomic nervous system, or the possibility that breath represents the movement of spirit in the body.

I continue to recommend breathwork to almost all the patients that I see. Breathing: The Master Key to Self Healing will teach you everything you need to know about the breathwork I use myself, and teach to the patients I work with in my medical practice.
