A decade ago, Deepak Chopra, M.D., wrote Perfect Health, the first practical guide to harnessing the healing power of the mind, which became a national bestseller. The book described how breakthroughs in physics and medicine were underscoring the validity of a 5,000-year-old medical system from ancient India known as Ayurveda ("the knowledge of life span" in Sanskrit). Perfect Health went on to describe how to apply the ancient wisdom of Ayurveda to everyday life. In celebration of this classic work we have created this new edition, revised and updated to include the latest medical research.
