Sachamama: ayahuasca ceremony at night. An arched ayahuasca vine - with hanging crystals - crowns the mesa (altar), where encantos (special power stones with healing properties), schacapa fans and large ceremonial pipes are. From left to right, Hernando (an estudiante curandero), don Ruperto Peña Shuña (centre) holding the bottle containing the brew and smoking a mapacho cigarro (hand-made cigar made with mapacho or jungle tobacco),  and don Francisco Montes Shuña (right), in front of a schacapa fan.
