Don Miguel Ruiz (born 1952), born Miguel Ángel Ruiz Macías, is a Mexican author of Toltec spiritual and personal development writing. His books draw on ancient teachings as a path to spiritual enlightenment, and they have found their warmest reception among readers of the New Thought movement; some associate his work with that of Carlos Castaneda, author of The Teachings of Don Juan.
Recognition has followed the readership: in 2018 Ruiz was named among the Watkins 100 Most Spiritually Influential Living People. He sits in that small company of spiritual writers whose ideas travel well beyond the shelves they are filed on – quoted, gifted between friends and returned to at intervals, which is its own kind of endorsement.
