Have you ever experienced the seemingly unconnected events coming to you when you are thinking about it?
For instance when you come across a word the meaning of which you do not know, the word keeps popping up quite frequently the same day?
Or when you think of some one coming to your home or when you anticipate something , not very assiduously and consciously, the person /the event turns up?
These incidents are not noticed by us immediately but one wonders about these things when one reflects upon it at a later date.
Do these have any meaning?
Well, Hinduism has an explanation.
Whatever is in the Macrocosm is in the microcosm.
That is whatever is on the Universe is present is with the individual.
Even the elements like Earth Water Fire Air and Ether that constitute the Universe is present in the individual .
Even the Electrons revolve around the Nucleus in the same way the cosmos moves around each other.
Every thing in the Universe is synchronised.
The actions,thoughts one performs/ has do not end with him.
They, being energy can not be destroyed.
They get stored in the Cosmos.
Even the most secret thoughts get stored in the Cosmos.They come back to the individual at some point of time.
This forms the basis of The Karma Theory of Hinduism.
In the same way events/persons which/ who are seemingly unconnected get connected without any serious effort.
Individual Consciousnees is a part of Universal Consciousness and the former is limitd by Space and Time, while the latter is unbounded.
This process of seemingly unconnected acusal events is
Called Synchronicity in modern Science, though it is under discussion and controversy.
Synchronicity is a concept, first explained by psychiatrist 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.” He introduced the concept as early as the 1920s but gave a full statement of it only in 1951

In 1952, he published a paper Synchronizität als ein Prinzip akausaler Zusammenhänge (Synchronicity – An Acausal Connecting Principle)[ in a volume which also contained a related study by the physicist and Nobel laureate Wolfgang Pauli.
Jung coined the word “synchronicity” to describe “temporally coincident occurrences of acausal events.”
In his book Synchronicity: An Acausal Connecting Principle, Jung wrote:
How are we to recognize acausal combinations of events, since it is obviously impossible to examine all chance happenings for their causality? The answer to this is that acausal events may be expected most readily where, on closer reflection, a causal connection appears to be inconceivable.
In the introduction to his book, Jung on Synchronicity and the Paranormal, Roderick Main wrote:
The culmination of Jung’s lifelong engagement with the paranormal is his theory of synchronicity, the view that the structure of reality includes a principle of acausal connection which manifests itself most conspicuously in the form of meaningful coincidences. Difficult, flawed, prone to misrepresentation, this theory none the less remains one of the most suggestive attempts yet made to bring the paranormal within the bounds of intelligibility. It has been found relevant by psychotherapists, parapsychologists, researchers of spiritual experience and a growing number of non-specialists. Indeed, Jung’s writings in this area form an excellent general introduction to the whole field of the paranormal.
In his book Synchronicity: An Acausal Connecting Principle, Jung wrote:
…it is impossible, with our present resources, to explain ESP, or the fact of meaningful coincidence, as a phenomenon of energy. This makes an end of the causal explanation as well, for “effect” cannot be understood as anything except a phenomenon of energy. Therefore it cannot be a question of cause and effect, but of a falling together in time, a kind of simultaneity. Because of this quality of simultaneity, I have picked on the term “synchronicity” to designate a hypothetical factor equal in rank to causality as a principle of explanation.
Synchronicity was a principle which, Jung felt, gave conclusive evidence for his concepts of archetypes and thecollective unconscious It described a governing dynamic which underlies the whole of human experience and history — social, emotional, psychological, and spiritual. The emergence of the synchronistic paradigm was a significant move away from Cartesian dualism towards an underlying philosophy ofdouble-aspect theory. It has been argued that this shift was essential to bringing theoretical coherence to Jung’s earlier work.
In his book Synchronicity (1952), Jung tells the following story as an example of a synchronistic event:
My example concerns a young woman patient who, in spite of efforts made on both sides, proved to be psychologically inaccessible. The difficulty lay in the fact that she always knew better about everything. Her excellent education had provided her with a weapon ideally suited to this purpose, namely a highly polished Cartesian rationalism with an impeccably “geometrical” idea of reality. After several fruitless attempts to sweeten her rationalism with a somewhat more human understanding, I had to confine myself to the hope that something unexpected and irrational would turn up, something that would burst the intellectual retort into which she had sealed herself. Well, I was sitting opposite her one day, with my back to the window, listening to her flow of rhetoric. She had an impressive dream the night before, in which someone had given her a golden scarab — a costly piece of jewellery. While she was still telling me this dream, I heard something behind me gently tapping on the window. I turned round and saw that it was a fairly large flying insect that was knocking against the window-pane from outside in the obvious effort to get into the dark room. This seemed to me very strange. I opened the window immediately and caught the insect in the air as it flew in. It was a scarabaeid beetle, or common rose-chafer (Cetonia aurata), whose gold-green colour most nearly resembles that of a golden scarab. I handed the beetle to my patient with the words, “Here is your scarab.” This experience punctured the desired hole in her rationalism and broke the ice of her intellectual resistance. The treatment could now be continued with satisfactory results.— Carl Jung, 
The French writer Émile Deschamps claims in his memoirs that, in 1805, he was treated to some plum pudding by a stranger named Monsieur de Fontgibu. Ten years later, the writer encountered plum pudding on the menu of a Parisrestaurant and wanted to order some, but the waiter told him that the last dish had already been served to another customer, who turned out to be de Fontgibu. Many years later, in 1832, Deschamps was at a dinner and once again ordered plum pudding. He recalled the earlier incident and told his friends that only de Fontgibu was missing to make the setting complete – and in the same instant, the now senile de Fontgibu entered the room.
Jung wrote, after describing some examples, “When coincidences pile up in this way, one cannot help being impressed by them – for the greater the number of terms in such a series, or the more unusual its character, the more improbable it becomes.”
