Synchronicities or "meaningful coincidences" represent Carl Jung's most exciting and controversial concept. They indicate that events in our inner world of dreams and fantasies can connect to physical events in the outer world and herald a fundamental turning point in our lives. The book brings together key articles by leaders in the field, as well as new chapters specially written for this volume. It will be an invaluable reference to all those interested in Jungian ideas, parapsychology, and the limits to consciousness. The book explores synchronicities from the perspectives of science, religion, archetypes, causality, meaning, extrasensory perception, and psychokinesis. It argues that we have overlooked our interconnectedness to the cosmos at the expense of our hunt for limited, reductionist explanations. Synchronicity speaks to the unification of humanity and the world.
