There are surprising similarities between Native American thought and Taoist thought. This is likely because Taoism arose out of the ancient shamanic traditions of China. I find these more valuable than the ten traditional commandments because it is a list of things you should do, rather than a list of prohibitions. I have no clue who the original author is, and you'll find different wordings on different web-sites.
