Synchronicity is when a sequence of apparently unrelated events that link to a theme or subject seem to take on a life of their own in your world. Everyone experiences synchroniticity at one time or another. Typically we don't slow down enough to work with the images or theme arising. But if we do pay attention, synchronicities can lead us to adventures, renewal, the next step, revelations, healing, crisis, or right-livelihood.
Synchronicity is a concept, first explained by psychoanallyst Carl Jung, which holds that events are "meaningful coincidences" if they occur with no causal relationship yet seem to be meaningfully related. During his career, Jung furnished several slightly different definitions of it. Jung variously defined synchronicity as an "acausal connecting (togetherness) principle," "meaningful coincidence", and "acausal parallelism."
