The book is based on a series of spiritual beliefs, held by Toltec`s seniors, to help readers transform their lives into a new experience of freedom, happiness and love.  According to the author, everything a man does is based on agreements he has made with himself, with others, with God and with life itself.  In these agreements, we can tell ourselves who they are, how to behave, what is possible and what is impossible.  Some agreements that create individuals may not cause problems, but there are certain arrangements that come from a place of fear and have the power to deplete emotional energy and reduce a person`s self-esteem.  The book states that these self-limiting agreements cause unnecessary suffering.  Ruiz also believes that to find personal joy, one must get rid of socially imposed and fear-based agreements that can unconsciously influence the individual`s behaviour and thinking.  Another fundamental premise of the book suggests that much of the suffering is created and that most people have the ability to transform themselves and the negative thoughts they have about the situations in their lives.  The author identifies the sources of unhappiness in life and proposes four beneficial agreements that can be concluded with oneself to improve their general state of well-being. By pacting with these four most important chords, an individual is able to dramatically influence the amount of happiness he feels in his life, regardless of external circumstances.  In addition to the book and audiobook, there is also an ebook, a four-colour picture book, a map deck and an online course.  The fourth agreement allows readers to have a better understanding of the progress made in achieving their goals in life. This agreement involves the integration of the first three agreements into daily life and the exploitation of its own potential.
 It is a matter of doing the best that can be managed individually, which varies from the different situations and circumstances that the individual may encounter. Ruiz believes that if you judge yourself and do your best at all times, you will be able to avoid remorse.  By integrating the first three chords and doing the best in all facets of life, the individual will be able to lead a life without grief or self-awareness.  The Four Agreements: A Practical Guide to Personal Freedom is a self-help book by best-selling author Don Miguel Ruiz with Janet Mills. The book proposes a code of conduct based on the ancient wisdom of Toltec, which advocates the freedom of self-limiting beliefs that can cause suffering and limitations in a person`s life. The third agreement describes the question of whether assumptions are made as to how it leads to suffering and why individuals should not participate in doing so. If you assume what others think, it can create stress and interpersonal conflict, because the person thinks that his hypothesis is a representation of the truth.  Ruiz believes that one solution to overcome the adoption act is to ask questions and ensure that communication between those involved is clear.  Individuals can avoid misunderstandings, sadness and drama by not taking any assumptions.  Ashley Rao, of the Survivor Assistance Program, wrote: « Regardless of where we will end up on the spiritual spectrum – from skeptics to believers and beyond religious beliefs – the application of Ruiz`s principles offers opportunities for transformation as part of our journey through mourning. »  Rachel Thompson of the HuffPost says the book « is a very useful book that can be put into practice in everyday practice by dealing with criticism of all kinds. » The book was originally published in 1997 by Amber-Allen in California.
