He went to medical school, and became a surgeon, until a near-death experience impelled him to seek answers in ancestral traditions of the Toltec in which his mother was a curandera (healer), and his grandfather a nagual (shaman) who, after death, continued to teach him in his dreams.
His most famous and influential work, The Four Agreements, was published in 1997. It advocates self-confidence and world peace through people making the following agreements with themselves, which he then discusses in depth.
Be impeccable with your word. (Don't lie.)
Don't take anything personally.
Don't make assumptions.
Always do your best.
Ruiz also wrote a workbook as a companion to the Four Agreements. He then wrote several other books, including "Beyond Fear" and "The Mastery of Love". In Beyond Fear he discusses some of his beliefs, including his belief in the legend of Atlantis, his belief that the sun entered its sixth age on January 11, 1992, which should lead to a new age for humanity, and his belief in the spiritual power of the pyramid of the sun at Teotihuacan. He can speak English and often lectures and leads retreats in the United States. Many of his students are American. In 2002 he suffered a massive heart attack, but has since recovered.
