In addition to demhur`s book and book, there is also an eBook, a four-colour picture book, a card game and an online course.  As far as ingratitude is concerned, this word certainly has the connotation of perfectionism, and if one takes it that way, one would indeed go mad. (Besides, the impeccability and other agreements you make with yourself, not the requirements that Ruiz imposes on you.) On the other hand, if you engage perfectly with your word as your goal, if you commit to be as honest and kind as possible with your words, without waiting for perfection of yourself or to fight if you are too short, this agreement could improve your well-being with yourself. Please read this book carefully. Wisdom is powerful, if you can hear it. I write this as Miguel Ruiz`s 10-year apprentice, before the publication of “The Four Accords”, an elder of his lineage, a divider of this wisdom… and the author of “The Everything Toltec Wisdom Book.” 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 living and sticking to good practices supported by modern psychology: we can use the fourth agreement, Do Your Best, to encourage us to aspire positively. But this agreement also recognizes that “our best” varies from time to time, depending on our circumstances and our state of mind. The awareness of this fact leads to the realization that everything we do is our best moment, and this awareness can prevent us from having flags of ourselves if we are not up to an inappropriate level of perfection. One of the most important teachings of wisdom in 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.
