The youngest of thirteen children, don Miguel Ruiz was born in rural Mexico to parents who were healers and practitioners of ancient Toltec traditions. As a young adult, he graduated from medical school and practiced neurosurger in Tijuana. A near-fatal car crash forever changed the direction of his life, however, causing him to leave medicine and to examine the essential truth about life and humanity. With his mother’s help, and through her ancestral teachings, he discovered his own path to awareness, which evolved into a deep understanding of the physical universe and the virtual world of the mind. Combining Toltec mythology and scientific perspectives, don Miguel has been able to merge ancient wisdom with modern physics and practical common-sense, forging a new philosophy for seekers of truth and personal authenticity. His landmark bestselling book, The Four Agreements, contains practical steps for long-term, personal transformation and has been read by millions around the world.
