Synchronicity is all too often tossed about describing events
[Sadly “Synchronicity” is all too often tossed about describing events which do not adhere to the synchronistic events as used within Depth Psychology.]
Synchronicity:
A phenomenon where an event in the outside world coincides meaningfully with a psychological state of mind.
Synchronicity . . . consists of two factors: a) An unconscious image comes into consciousness either directly (i.e., literally) or indirectly (symbolized or suggested) in the form of a dream, idea, or premonition. b) An objective situation coincides with this content. The one is as puzzling as the other.[“Synchronicity: An Acausal Connecting Principle,” ibid., par. 858.]
Jung associated synchronistic experiences with the relativity of space and time and a degree of unconsciousness.
The very diverse and confusing aspects of these phenomena are, so far as I can see at present, completely explicable on the assumption of a psychically relative space-time continuum.
As soon as a psychic content crosses the threshold of consciousness, the synchronistic marginal phenomena disappear, time and space resume their accustomed sway, and consciousness is once more isolated in its subjectivity. . . . Conversely, synchronistic phenomena can be evoked by putting the subject into an unconscious state.[“On the Nature of the Psyche,” CW 8, par. 440.]
Synchronicity was defined by Jung as an “acausal connecting principle,” an essentially mysterious connection between the personal psyche and the material world, based on the fact that at bottom they are only different forms of energy.
It is not only possible but fairly probable, even, that psyche and matter are two different aspects of one and the same thing. The synchronicity phenomena point, it seems to me, in this direction, for they show that the nonpsychic can behave like the psychic, and vice versa, without there being any causal connection between them.[Ibid., par. 418.]
Carl Jung on “Synchronicity” – Anthology

We should be particularly watchful when synchronous events occur for a numen is then in sight. In a certain mood one notices that the crows fly towards the left. When an archetypal event approaches the sphere of consciousness, it also manifests itself in the outer life. ~Carl Jung, Conversations with C.G. Jung, Page 51
Synchronous events are widely accepted in Chinese philosophy and are the basis of astrology. ~Carl Jung, Conversations with C.G. Jung, Page 51.
When someone is under a grave threat, and the archetypes are constellated, synchronistic situations can arise — events that are independent of him, existing in the outside world. ~ Carl Jung, Conversations with C.G. Jung, Page 51.
My further writing led me to the archetype of the God-man and to the phenomenon of synchronicity which adheres to the archetype. ~Carl Jung, Letters Vol. 1, Pages 479-481.
This means that when we observe statistically we eliminate the synchronicity phenomenon, and conversely, when we establish synchronicity we must abandon the statistical method. ~Carl Jung, Letters Vol. 1, Pages 546-548.
The statistical method of science stands in a relationship of complementarity to synchronicity. This means that when we observe statistically we eliminate the synchronicity phenomena and. . . when we establish synchronicity we must abandon the statistical method. ~Carl Jung, Letters Vol. 1, Page 548.
Synchronicity states that a certain psychic event is paralleled by some external non-psychic event and that there is no causal connection between them. It is a parallelism of meaning. ~C.G. Jung Speaking, Page 387.
Synchronicity means the simultaneous occurrence of a psychic state with one or more external events, which appear as meaningful parallels to the momentary subjective state. ~Carl Jung, CW 8, Page 441.
Just as a causality describes the sequence of events, so synchronicity to the Chinese mind, deals with the coincidence of events. ~Carl Jung, CW 11, Page 593.
The method like all divinatory or intuitive techniques is based on an acausal or synchronistic connective principle. ~Carl Jung, CW 8, Page 452.
The main difficulty with synchronicity (and also with ESP) is that one thinks of it as being produced by the subject, while I think it is rather in the nature of objective events. ~Carl Jung, Letters Vol. II, Page 181.
The coincidence of the Fibonacci numbers (or sectio aurea) with plant growth is a sort of analogy with synchronicity inasmuch as the latter consists in the coincidence of a psychic process with an external physical event of the same character or meaning. ~Carl Jung, Letters Vol. II, Pages 287-289.
Where an archetype prevails, we can expect synchronistic phenomena, i.e., acausal correspondences, which consist in a parallel arrangement of facts in time. The arrangement is not the effect of a cause. ~Carl Jung, Letters Vol. II, Pages 43-47.
Concerning the omniscience it is important to know that Adam already was equipped with supernatural knowledge according to Jewish and Christian tradition, all the more so Christ. I think that the great split in those days was by no means a mistake but a very important collective fact of synchronistic correspondence with the then new aeon of Pisces. ~Carl Jung, Letters Vol. II, Pages 163-174
An American pupil of mine, Dr. Progoff (New York), has tried to adapt and to explain synchronicity to the average reader but he landed his ship on the rocks because he could not free his mind from the deep-rooted belief in the Sanctissima Trinitas of the axiomata time, space, and causality. ~Carl Jung, Letters Vol. II, Pages 215-216.
I have got stuck, on the one hand, in the acausality (or “synchronicity”) of certain phenomena of unconscious provenance and, on the other hand, in the qualitative statements of numbers, for here I set foot on territories where I cannot advance without the help and understanding of the other disciplines. ~Carl Jung, Letters Vol. II, Pages 351-352.
The principle of synchronicity represents the essential particularity of a non-statistical world, where facts are not measured by numbers but by their psychological significance. ~Carl Jung, Letters Vol. II, Pages 373-375
I think you are correct in assuming that synchronicity, though in practice a relatively rare phenomenon, is an all-pervading factor or principle in the universe, i.e., in the Unus Mundus, where there is no incommensurability between so-called matter and so-called psyche. ~Carl Jung, Letters Vol. II, Pages 398-400
With regard to the horoscope I have serious doubts whether it can be understood as a purely synchronistic phenomenon, for there are unquestionable causal connections between the planetary aspects and the powerful effects of proton radiation, though we are still very much in the dark as to what its physiological effects might be. ~Carl Jung, Letters Vol. II, Pages 420-421
