A bestseller in its original edition, The Natural Mind was Dr. Andrew Weil's first book and the philosophical basis for all of his resulting beliefs and tenets on health, healing, and the mind. Now completely revised and updated for the twenty-first century, The Natural Mind suggests that the desire to alter consciousness periodically is an innate, normal human drive. A landmark in his career, and in America's approach to the drug problem in general, The Natural Mind is essential reading for anyone interested in Andrew Weil's philosophy of integrative medicine and optimum health.
