Book ~ "The Four Agreements: A Practical Guide to Personal Freedom" (2001) Don Miguel Ruiz

From Amazon.com ~ 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.

I read about this book on B's blog a couple weeks ago.

It's fairly religious at times (I'm not) but I liked the concepts. There are 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. 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 courage 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 from moment to moment; it will be different when you are healthy as apposed to sick. Under any circumstances, simply do your best and you will avoid self-judgment, self-abuse and regret.
