This volume includes the essays from "On Psychic Energetics and the Nature of Dreams" as well as other works by the author that belong to the same thematic area. The book essentially contains a summary of the theoretical foundations of Analytical Psychology from the time of Jung's separation from Freud. In doing so, the author articulated his research results and new insights. The development of Jung's independent and clear concepts was not, in itself, a definitive engagement with the various psychological directions and theories. Over the years, his insights increasingly transcended the boundaries of what had previously been presented in psychology. They culminated in the groundbreaking paper on "Synchronicity, an Acausal Connecting Principle," which is included as the concluding chapter of the volume.
