Readers will learn about Leary’s encounters with 20th-century groups and figures like Ram Dass, the Weather Underground, the Black Panthers, and Robert Anton Wilson, all of whom influenced his psychic explorations and the development of his eight-circuit model for understanding altered states of consciousness and the potential for transcendent experiences. Flatley also details the role of the tarot in Leary’s life and philosophy, showing how Leary created his own version of the deck, which is featured in this book. Flatley then reveals the correspondences between Leary’s deck and his eight-circuit model of consciousness and guides readers on how to use this tarot for divination.
