Synchronicity is a word coined by the Swiss psychologist Carl Jung to describe the "temporally coincident occurences of acausal events". Jung also spoke of synchronicity as being an "acausal connecting principle" (ie. a pattern of connection that is not explained by causality). Plainly put, it is the experience of having two (or more) things happen simultaneously in a manner that is meaningful to the person or people experiencing them, where that meaning suggests an underlying pattern. It differs from coincidence in that synchronicity implies not just a happenstance, but an underlying pattern or dynamic that is being expressed through meaningful relationships or events. It was a principle that Jung felt compassed his concepts of archetypes and the collective unconscious, in that it was descriptive of a governing dynamic that underlay the whole of human experience and history—social, emotional, psychological, and spiritual. Jung believed that many experiences perceived as coincidence were due not merely to chance, but instead, suggested the manifestation of parallel events or circumstances reflecting this governing dynamic1.
