The Four Agreements Toltec Wisdom Collection: 3-Book Boxed Set (Paperback)

According to Amazon.com Review
Sit at the foot of a native elder and listen as great wisdom of days long past is passed down. In The Four Agreements shamanic teacher and healer Don Miguel Ruiz exposes self-limiting beliefs and presents a simple yet effective code of personal conduct learned from his Toltec ancestors. Full of grace and simple truth, this handsomely designed book makes a lovely gift for anyone making an elementary change in life, and it reads in a voice that you would expect from an indigenous shaman. The four agreements are these: Be impeccable with your word. Don’t take anything personally. Don’t make assumptions. Always do your best. It’s the how and why one should do these things that make The Four Agreements worth reading and remembering. –P. Randall Cohan –This text refers to the Paperback edition.

The Voice of Knowledge reminds us of a profound and simple truth: The only way to end our emotional suffering and restore our joy in living is to stop believing in lies — mainly about ourselves.
