Rooted in traditional Toltec beliefs, these four agreements are essential steps on the path to personal freedom: Be impeccable with your word; Say only what you mean; The word is the most powerful tool humans have; Don't take anything personally; Self-importance leads people to think they are the center of the universe, causing pain and injustice; Don't make assumptions. To avoid frustration and blame, ask what is meant; Always do your best. This is the surest way to avoid self- condemnation, though it is important to realize one's best is always changing.
