His best-known book, The Four Agreements, was published in 1997 and has sold about 10 million times in the United States and has been translated into 46 languages. The book advocates the personal freedom of convictions and agreements we have made with ourselves and with others, which create use and unhappiness in our lives.  It was broadcast on the television show Oprah.  The four chords are: the first chord emphasizes the meaning of our words and how they influence the world around us. This suggests that we must speak honestly and with integrity and never have to make false promises or statements. Second, we must speak with love when we talk about others and ourselves. The words you use to speak to yourself create your belief system and the arrangements you have with yourself. If these are positive chords, it allows you to have more self-esteem. Avoid gossip. Instead, always use your word for truth and love. We all live in our own minds and act according to our own agreements. Other people say, think and act according to what is happening in them. You may have feedback that rubs you in the wrong way or hears someone say something emotional, but you need to remember that nothing another person says or does, whether it`s you or not, never goes through you.
Like language, we don`t have much choice in the agreements that have been passed down to us by our family or culture. All the agreements we have made with ourselves, whether we know them or not, are inherited from our belief system, and our belief system controls our lives. If you want to change your life, you have to change your chords. Living life to the fullest and having gratitude for the gifts in your life will allow you to live free from fear and open your mind, body and soul to begin your healing process. Practicing the four chords in our lives is part of our process of growth and change. We can transform our reality for the better by combining agreements on a daily basis in order to achieve a calmer way of life. It is not always easy to guarantee agreements. Although these agreements open your eyes to a more positive, more promising way of life, it is a challenge to overcome the resistance of the mind and live each chord 100%. “The Four Agreements” is a book by best-selling author Don Miguel Ruiz. Popular and influential, this book says that the way people think and act has everything to do with the “agreements” they make with themselves. These agreements could also be described as belief systems or entrenched attitudes.
While people drink or do drugs, their attitudes are often negative or selfish. The four agreements offer alternative life, thought and language opportunities that are more in line with a healthy and happy lifestyle.
