The second agreement offers readers the opportunity to manage the hurtful treatments of others that they can experience in life. She argues that it is important to have a strong self-concept and not to have to rely on the opinions of others to be satisfied and satisfied with their self-concept. This agreement also allows readers to understand the idea that each individual has a unique vision of the world that changes his or her own perception and that a person`s actions and beliefs are a projection of his or her personal reality.  Ruiz believes that anger, jealousy, envy and even sadness can subside or dissipate as soon as an individual stops taking things in person.  One day we become our own servants. We don`t even need authority to threaten or punish us. Our belief system – the book of law – governs our minds. The book of law is made up of all the agreements that we have accepted as truth. Despite its limitations, the book of law gives us the feeling of being safe. It is our understanding of how the world works, and it represents order in a world of chaos. We may not have chosen those agreements, but we have approved them.
And they don`t change so easily – defying our own beliefs requires courage. As you can see from the examples above, when we hear and believe an opinion, we form an agreement. The opinion is growing. The verdict will be part of us. Black Magic created a spell that was hard to break. The agreements we have accepted create an inner judge and an inner victim. Ruiz explains that this agreement is certainly the most important, but that the most difficult thing is to respect it.  For this agreement, Ruiz first analyzes the word «irreprocible.» The perfectly irreproachable word comes from the Latin word peccatus, which means «sin,» and the term «im» at the beginning of blame is the Latin prefix meaning «without.» Ruiz describes a sin as all that goes against himself, and therefore to be impeccable with language is to assume the responsibility of one and without judgment against oneself and against the other.
 This agreement focuses primarily on the importance of speaking with integrity and carefully choosing the words before saying it out loud.  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.  By accepting the four chords that have been outlined in this book, we are drinking the fog and we are beginning to see ourselves – and others – in a clearer and more understanding way. 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 itself is created and that most people have the ability to themselves and negative thoughts that s
