I cannot judge this book as a book on shamanism, but as a business book it is very basic, to me personally, practically useless. As a book on power, it hardly scratches the surface. If you want to understand power, wether in politics, negotiation, business or in personal life, much better options would be two books by Robert L. Dilenschneider "On Power" and "Power and Influence", "The 48 Laws of Power" by Robert Greene and "Power Plays" by Robert Mayer. Hey, it seems that Roberts are the experts on power, or could it be some sort of covert shamanic plot? Hmm....
