Ancient traditions maintain that we contain a "subtle body," a psychospiritual entity of several layers through which the aspirant seeks knowledge of the self and God. As Maureen Lockhart explains here, the practices and disciplines that evolved from an awareness and understanding of the subtle body—the material and nonmaterial working together—form a coherent system of transformation that is central to the beliefs of Buddhists, Gnostics, Sufis, and Native Americans. Finding common links between yoga, acupuncture, and Ayurveda, Lockhart also suggests that this synthesis of traditional and contemporary healing practices could lay the foundation for the medicine of the future. The book's 32 pages of color illustrations bring together excellent selections from both Eastern and Western art.
