Serge Kahili King, author of "Urban Shaman," explains the principles of Huna, the Polynesian philosophy of esoteric knowledge and practice. I love Huna. It is the Adventure side of Shamanism. I try to put these principles into every part of my life.
I would highly recommend to you this book as well. Which you can buy from http://www.huna.net/HBM/Books/hbooks2.html The teachings from the above videos are expanded upon in this book.
