In his book The Four Agreements, Don Miguel Ruiz reveals the course of self-limiting beliefs that rob us of joy and create needless suffering. Based on ancient Toltec wisdom, The Four Agreements offers a powerful code of conduct that can rapidly transform our lives to a new experience of freedom, true happiness and love. Here are the four agreements.

Be impeccable with your word.
Speak with integrity. Say only what you mean. Avoid using the word to speak against yourself or to gossip about others. Use the power of your word in the direction of truth and love.
Don't take anything personally.
Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions and actions of others, you won't be the victim of needless suffering.
Don't make assumptions.
Find the course to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness and drama. With just this one agreement, you can completely transform your life.
Always do your best.
Your best is going to change fomr moment to moment; it will be different when you are healthy as opposed to sick. Under any circumstance, simply do your best, and you will avoid self-judgment, self-abuse and regret.

Don Miguel Ruiz joins his son, Don Jose Ruiz, to offer a fresh perspective on The Four Agreements, and a powerful new agreement for transforming our lives into our personal heaven: The Fifth Agreement. The Fifth Agreement takes us to a deeper level of awareness of the power of the Self, and returns us to the authenticity we were born with.
Be skeptical, but learn to listen.
Don't believe yourself or anybody else. Use the power of doubt to question everything you hear: Is it really the truth? Listen to the intent behind the words, and you will understand the real message.
