I've always wondered about things like why, when the package says that no purchase is necessary to enter the contest, the details are inside. Does that mean that if you rip up the package to read the details you don't have to purchase it? And what would the shopkeeper think about that?

As for the book "Hanta Yo" -- one reason the list of words is there is because it's a novel -- a work of *fiction.* Made up from the researchs, knowledge, and mind of Ruth Beebe Hill. This is not to say that the ideas aren't valuable or meaningful -- just don't quote it in a dissertation or assume that it is a significant, primary source to Lakotah thought and culture. (A Google search of "Hanta Yo" turned up lots of martial arts links and more than a few tattoo parlors as well as a few links to the book.)
