This collection of essays, written by the poster boy of 1960s counterculture, describes the psychological journey Timothy Leary made in the years following his dismissal from Harvard, as his psychedelic research moved from the scientific to the religious arena. He discusses the nature of religious experience and eight crafts of God, including God as hedonic artist.

Leary also examines the Tibetan, Buddhist, and Taoist experiences. In the final chapters, he explores man as god and LSD as sacrament.
