For more than 20 years Alan Shoemaker apprenticed with shamans in Ecuador and Peru, learning the traditional methods of ayahuasca preparation, the ceremonial rituals for its use, and how to commune with the healing spirit of sacred plant allies. Now a recognized ayahuasquero, he offers an insider’s account of the traditions of his two foremost teachers and mentors, Don Juan in the Peruvian Amazon, an ayahuasquero, and Valentin in Ecuador, a San Pedro shaman.
