Book excerpt: Millions of readers of Carlos Castaneda books have long enjoyed the fantastic teachings of don Juan Matus, the Yaqui shaman from northern Mexico. Now, thanks to the practical techniques based on Castaneda's writings offered here by author Victor Sanchez--the body as a field of energy, the not-doings of the personal self, stopping the internal dialogue, the magic of attention, setting up dreaming, the warrior's greatest love, and more--you can apply these teachings to your everyday life.
