More about the Toltec civilization can be found in the Ancient History Encyclopedia.
Ruiz's short book, The Four Agreements, spent several years on the NYT best sellers list. Apparently, a lot of us are searching for simple truths and a little more agreement in our lives.
Instead of following his family's Toltec healing tradition, Ruiz went to medical school and became a surgeon, like several other authors* I enjoy. Coincidence? OK. Or maybe I have a thing for writers influenced by their near-death experiences. Hm.
Is this self-help book worth a read? Well, if you're looking for a headache cure and suspect the answer might lie within your own head, yep. Definitely worth reading.
The Four Agreements are:
1. Be Impeccable with your Word
2. Don’t Take Anything Personally (Less Spock-like than it sounds)
3. Don’t Make Assumptions
4. Always Do Your Best (Don't worry, no Tiger-mom stuff here. Think Stuart Smalley instead. Your best will vary with your health, mood, energy level - and that's OK.)
My thoughts? If you're looking for answers - or just about anything - you can find it in a book :D
