Thank you, Allan, for sharing your wisdom. I am honored that someone of your stature would take the time to read my article and clarify the importance of the agreements. I interpreted “is” as living in the present and “was” the representation of past behaviors. Tension change probably intentionally. The best way to develop knowledge is to bypass other evaluations and read the material and develop your own knowledge. Because I also look at topics in relation to me My opinion is that we all get something different from any book, based on completely different emotional reactions, based on the observations of a group that reads all four chords at the same time. There were about 50 of them, and I recommended it to a brother and sister who had a childhood trauma. He read the first chapters in tears, but he understood the healing power in himself. The first one only me off, but I understood that he was drawing why we shouldn`t believe that way. Be immaculate with your word.
Don`t take anything personal. Don`t make any assumptions. Always do your best. The light and the truth. 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.
 If your beliefs create in you a deep happiness, then I say: Keep them. If they cause trouble, if the beliefs of others are different, consciousness can leave you with the choice of what you believe and what you let go. Many of our convictions, our concepts, our agreements were nourished to us as “truth” when we were young, and we accepted them literally and completely. The beginning of the four chords is about how we were domesticated by our caregivers in a “dream” of life. The only dream they gave us was the one they lived, which they received most often from their parents, etc. I also found it strange to judge a book about the behavior of a person who claims to have read it and about the elderly who are the ancestors of the author of the book. That is why I did not respond to Cccc`s comment. If the commentator explains why he/she thought the four chords meant that people were behaving ruthlessly and selfishly, I might have received an answer.
As things stand, I agree with the idea that, toltec or not, these principles are a healthy way of life, and correspond to good practices supported by modern psychology: one of the most important teachings of wisdom of the Toltec tradition is that we all dream — to dream of a unique vision and experience of the universe. It`s at the beginning of “The Four Accords,” and my experience is that a lot of people slip into that part and go to the chords. 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.
