First line: Thousands of years ago, the Toltec were known throughout southern Mexico as "women and men of knowledge."
Why you should read this book: A lot of people claim that it changed their lives. In repetitive and dreamlike language, it lays out a system of explanation as to why you, the reader, are unhappy, and how to find happiness by adhering to four simple beliefs about how to think and act. Just speak kindly, don't take things personally, don't make assumptions, and always do your best, and you will transform this world from hell to heaven.
Why you shouldn't read this book: The provenance of the "Toltec" is unclear (getting some Carlos Castenda vibes here) and there's a New-Agey quality in the instructions.
