The problem of synchronicity has puzzled me for a long time, ever since the middle twenties, when I was investigating the phenomena of the collective unconscious and kept on coming across connections which I simply could not explain as chance groupings or "runs." What I found were "coincidences" which were connected so meaningfully that their "chance" concurrence would represent a degree of improbability that would have to be expressed by an astronomical figure.
Carl JungThere are two reasons why man loses contact with the regulating center of his soul. One of them is that some single instinctive drive or emotional image can carry him into a one-sidedness that makes him lose his balance...his one-sidedness and consequent loss of balance are much dreaded by primitives, who call it 'loss of soul.' Another threat...circles around particular complexes
