Synchronicities or 'meaningful coincidences' represent one of Carl Jung's most exciting, controversial and far-reaching ideas. When our inner world of dreams and fantasies suddenly connect to events in the outer world it can herald a major turning point in our lives. The book brings together the key articles on synchronicity written by leaders in the field of parapsychology and Jungian psychology, as well as new chapters specially produced for this volume. "Synchronicity" will be an invaluable reference for all those interested in Jungian ideas, parapsychology, the limits to consciousness and the mysterious nature of our inner worlds. This book explores the nature of synchronicities from a wide variety of perspectives including science, religion, extra-sensory perception and psychokinesis.It investigates the role of the archetypes, the limits to scientific causality and the way in which synchronicities can open a door into the numinous and speak to the unification of humanity and the world. "Synchronicity" also reveals how we have forgotten our inter-connectedness to the cosmos at the expense of our desire for limited and reductionist explanations.
