Ruiz's explanations of Toltec-based cosmography got a major boost recently when publishing pooh-bah Oprah Winfrey mentioned his work on her TV show. Ruiz, whose workshop teachings are distilled here, was born into a Mexican family of traditional healers, became a surgeon in adulthood, then underwent a near-death experience that made him reexamine his life, his beliefs. Like the popular works of the late Carlos Castaneda, Ruiz's teachings focus on dreams and visions. "Dreaming," Ruiz argues, "is the main function of the mind." A series of four "agreements" are detailed, which make up a larger picture of unconditional human faith. Despite the New Age- sounding language, Ruiz is refreshingly clear in the presentation of his ideas. Reading aloud, actor Coyote sounds every bit the enthusiastic old hippie, genuinely excited by the concepts he is spinning. Based on the 1997 Amber-Allen edition. (Sept.)
