After more than 450 years of European intrusions into South America's rainforest, small groups of people across Europe now gather discreetly to participate in Amazonian ceremonies their local governments consider a criminal act. As devotees of a new Brazil-based religion called Santo Daime, they claim that they contact God by way of ayahuasca, a potent psychoactive beverage first developed by native communities in pre-Columbian Amazonia. This bitter, brown liquid is a synergy of plants containing DMT, a mind-altering chemical classified as an illicit "hallucinogen" in most countries. By contrast, Santo Daime members ( ) revere ayahuasca as a sacrament, combining it with rituals and theologies borrowed from Christian mysticism, indigenous shamanism, Afro-Brazilian spiritualism, and Western esotericism.The Santo Daime religion was founded in 1930 by an Afro-Brazilian rubber tapper named Raimundo Irineu Serra, now known as (Master) Irineu. Presenting results from more than a year of fieldwork with Santo Daime groups in Europe, Marc G. Blainey contributes new understandings of contemporary Westerners' search for existential well-being on an increasingly interconnected planet. As a thorough exploration of daimistas' beliefs about the therapeutic potentials of ayahuasca, this book takes readers on an ethnographic journey into the deepest recesses of the human psyche.
