The uncanny coincidence. The unlikely conjunction of events. The startling serendipity. Who hasn’t had it happen in their life? You think of someone for the first time in years, and run into them a few hours later. An unusual phrase you’d never heard before jumps out at you three times in the same day. On a back street in a foreign country, you bump into a college roommate. Maybe a book falls off the shelf at the bookstore and it is
exactly what you need.
Carl Jung believed it was a glimpse into the underlying order of the universe. He coined the term synchronicity to describe what he called the “acausal connecting principle” that links mind and matter. He said this underlying connectedness manifests itself through meaningful coincidences that cannot be explained by cause and effect. Such synchronicities occur, he theorized, when a strong need arises in the psyche of an individual. He described three types that he had observed: the coinciding of a thought or feeling with an outside event; a dream, vision or premonition of something that then happens in the future; and a dream or vision that coincides with an event occurring at a distance. No one has come up with a definition that has superceded his, although there has been debate on whether events linked to precognition and clairvoyance should be included as synchronicity.
Some scientists see a theoretical grounding for synchronicity in quantum physics, fractal geometry, and chaos theory. They are finding that the isolation and separation of objects from each other is more apparent than real; at deeper levels, everything — atoms, cells, molecules, plants, animals, people — participates in a sensitive, flowing web of information. Physicists have shown, for example, that if two photons are separated, no matter by how far, a change in one creates a simultaneous change in the other.
Synchronicities are sometimes regarded as signs, and some people consciously use them to make decisions in life. In the novel The Celestine Prophecy, a bestseller which thrust synchronicity into the public consciousness, James Redfield says that all coincidences are significant because they point the way to an unfolding of our personal destiny.
