Don Miguel Ruiz was born into a family of healers, and raised in rural Mexico by a curandera (healer) mother and a nagual (shaman) grandfather. The family anticipated that Miguel would embrace their centuries-old legacy of healing and teaching, and carry forward the esoteric Toltec knowledge. Instead, distracted by modern life, Miguel chose to attend medical school and become a surgeon.

A near-death experience changed his life. Stunned by this experience, he began an intensive practice of self-inquiry. He devoted himself to the mastery of the ancient ancestral wisdom, studying earnestly with his mother, and completing an apprenticeship with a powerful shaman in the Mexican desert. In the tradition of the Toltecs, a nagual guides an individual to personal freedom.

Don Miguel is a nagual from the Eagle Knight lineage, and is dedicated to sharing his knowledge of the teachings of the ancient Toltecs. He is the author of The Four Agreements, The Mastery of Love, and The Four Agreements Companion Book.
