Originally published in 1982, draws on the author's wide experience of occultism, western magic and anthropological knowledge of shamanism, to explore the interesting parallels between traditional shamanism and the more visionary aspects of magic in modern western society. In both cases, as the author shows, the magician encounters profound god-energies of the spirit, and it is up to the individual to interpret these experiences in psychological or mythological terms. The book demonstrates that both shamanism and magic offer techniques of approaching the visionary sources of our culture.
