Andrew Weil, the guru of complementary medicine and author of Spontaneous Healing, offers a healing technique that is not only free, but can be done anywhere, any time: breathing. "Wherever you have nerves," says Dr. Weil, "You have the opportunity for improvement using breath work." The first CD of this set is a clear lecture about the benefits of conscious breathing, its spiritual roots (prana yoga), the physiological rationale, the emotional connection, and examples from his medical practice. On the second CD, Weil offers eight separate exercises, starting with just noticing the breath, the reaction of the body, and how the mind tends to wander. Although the mind will constantly be distracted by worries, aches and pains, and emotional turmoil, Weil advises, just come back to following the breath. As you progress through the exercises, you'll learn more advanced techniques, like quick in-out breathing through the nose (a speedy pick-me-up). During most practice sessions, you'll hear "silence" or Weil's own breathing. Other practice sessions offer relaxing music (Eastern-flavored with flute and drone) by Mark McCoin. Most exercises are specifically that -- sit up straight and practice, using active imagination -- but many principles can be applied during the course of the day. "You can't always control your emotions," says Weil, "but you can control your breathing.... Pay attention to the breath to put the brain in a neutral place." Weil's advice: Aim for slower, deeper, quieter, and more regular.
