This is a truly amazing book, creating it's own journey in your mind when you are ready for the information it contains.
The 21 chapters are each a gem of insights and relative real-world experiences of the author. For example: Chapters 17 & 18 on the Magic Secret - Huna can open doors that otherwise are unseen.
The personal stories of people affected, and proving, the materials will help the reader. As this is written, copies are available on Amazon at $99 for the original edition; and $39 and up for a '1996 edition' which I've not seen.
