In this book, Jung argues for a reevaluation of the symbolism of Alchemy as being intimately related to the psychoanalytical process. Using a cycle of dreams of one of his patients he shows how the symbols used by the Alchemists occur in the psyche as part of the reservoir of mythological images drawn upon by the individual in their dream states. Jung draws an analogy between the Great Work of the Alchemists and the process of reintegration and individuation of the psyche in the modern psychiatric patient.
