In the Foreword and Introduction, Carlos Castaneda clarifies that his books document don Juan Matus’s unique teaching method for understanding the “sorcerers’ world,” a rigorous form of “oral instruction and manipulation of awareness” that is as complex as formal academic training. Don Juan, unable to find a perfect term, settled on “sorcery” to describe this knowledge, emphasizing that it’s not about learning new concepts but about “saving energy.” This conserved energy allows sorcerers to perceive a “modality of the time” beyond ordinary perception, tapping into “energy fields” inaccessible to average individuals whose energy is fully deployed in their everyday world. This “state of awareness,” or “silent knowledge,” is cultivated by a teacher (the “nagual”) who convinces the apprentice of their inherent power, facilitating a “direct knowing” without words, and is broadly categorized into the “mastery of awareness,” the “art of stalking,” and the “mastery of intent.”
