The author is a shaman and huna philosopher.
Huna is an ancient philosophy going back 2,000 years, and contains many self realization techniques, including the unification of the three selves, removing emotional blocks and fears, and manifesting your goals. There is also an energy practice which uses the power of focus.
This book goes through the 7 rules of the Huna Philosophy, aka The Shamanic Principles, explaining them in some detail. It is an ancient belief system, and also an amazing self improvement system which I wholeheartedly recommend.
The world is what you think it is i.e there is no reality only perception. There are no limits. Energy flows where attention goes are three of the rules.
There are many self help books out there which focus on individual concepts, which seem new, yet are all contained within this philosophy, which is over 2,000 years old. I am thinking of books such as the Power of Intention, and the Power of Now, Unlimited power.
In addition the concepts of the conscious, subconscious, and superconscious or universal mind, have been around for thousands of years, yet only since the early 1900s with the writings of those such as Carl Jung have these ideas become more widely accepted.
This philosophy does enable you to combine your three selves, and clear emotional blocks and limiting beliefs for improved effectiveness.
There are excellent healing practices and visualizations within this book. Many of our illnesses spring from our unresolved emotions, whereas much of western medicine treats the symptom not the cause. I believe energy practice is very important for focus, as energy flows where attention goes.
Many other philosophies share common roots with this one. One of the main differences is this a can do not a can't do philosophy. To use one of the beliefs, there are no limits. When you buy this book your journey is only beginning because you will want to learn more.
I wonder if this was helpful.
