Tarot and the Archetypal Journey offers a robust, Jungian approach to understanding the tarot, using archetypes and techniques such as word association, active imagination, and dialogue. She reveals how the cards reflect universal symbols and psychological truths, offering insights into human nature and personal transformation. Drawing connections to mythology, the arts, and the humanities, Nichols shows how the Major Arcana can be seen as a map of life—one that mirrors the hero's journey and guides each of us toward self-awareness and wholeness.

Sallie Nichols taught Symbolism of the Tarot for trainees at the C.G.Jung Institute, Los Angeles. In a series of seminars entitled "A Tarot Trip into Jung's Psychology," presented at the Theosophical Center in Hollywood and elsewhere, she successfully introduced both the Tarot and Jung's concept of the archetypes to audiences relatively unfamiliar with either subject.
