In exploring the manifestations of human spiritual experience both in the imaginative activities of the individual and in the formation of mythologies and of religious symbolism in various cultures, C. G. Jung laid the groundwork for a psychology of the spirit. The excerpts here illuminate the concept of the unconscious, the central pillar of his work, and display ample evidence of the spontaneous spiritual and religious activities of the human mind. This compact volume will serve as an ideal introduction to Jung's basic concepts.
