Exploring prominent churches and cults in depth, he examines the lives of their colorful leaders, the origins of their unorthodox beliefs, the controversial practices of their congregants, and their many conflicts with both law enforcement and public opinion. He looks at the Native American Church and their legal battle over their peyote rituals, the cannabis sex temple known as the Psychedelic Venus Church, the murderous end of the LSD-therapy cult known as the Church of Naturalism, and several other major groups and temples of psychedelic spirituality. He then offers an encyclopedic survey of dozens of minor organizations, many of which have never before been documented in an authoritative source. Sharing personal interviews and anecdotes about the strange outrageous adventures of religious psychonauts alongside rare photos and illustrations, this extensively researched study of underground psychedelic religious sects in the United States reveals their spiritual and cultural influence from the 1960s to the present day.
