Synchronicity ,what is it?

Synchronicity is the experience of two or more events which occur in a meaningful manner, but which are causally un-related. In order to be synchronous, the events must be related to one another conceptually, and the chance that they would occur together by random chance must be very small.
One personal example about synchronicity.I was doing some channeling and writing .At the end i asked who is communicating he said Marco.Two days later i was channeling and writing again and i asked who is speaking he said Polo. I felt extremely confused.I talked about this with a couple of people,search in the Internet about Marco Polo,nothing made sense.Two days later a get a mail from someone, telling me that she added me to her buddy list.I checked out who is this person because my account at this website was inactive for six months.I checked her blogs and find SYNCHRONICITY.This is what i found. "Earl was trying to track down an out-of-print book called The Adventures of Marco Polo. He scoured two used book stores in New York City, had no success, and caught a taxi to a third. The cab driver was unusually chatty, and during their conversation, Earl glanced at his license on the dashboard. His name? Marco Polo!". Another story .My sister was waiting for her daughter for 20 minutes in NYC.She tried to call her but she didn't answer.A couple approached her and asked her about certain address.She explained them how to get there.Immediately after her daughter called and asked her Where are you Mom? My niece said you're in the wrong place and explained her how to get there.When she arrived and looked at the address,was exactly the same address that the couple asked before.
Synchronicities are people, places or events that your soul attracts into your life to help you evolve to higher consciousness or to place emphasis on something going on in your life. The more 'consciously aware' you become of how your soul manifests, the higher your frequency becomes and the faster you manifest positively. Each day your life encounters meaningful coincidences, synchronicities, that you have attracted, on other words created in the grid of your experiences in the physical. Souls create synchronicities, played out in the physical. It is why you are here. It is how our reality works.
The intellect has little to do on the road to discovery. There comes a leap in consciousness, call it Intuition or what you will, the solution comes to you and you don't know how or why.
Albert Einstein.
“I am open to the guidance of synchronicity, and do not let expectations hinder my path.”
Dalai Lama.

My personal point of view is things happens constantly but we don't see or we ar not alert.
Do you remember the story about newton with the apple? apples always falls every day every second. Gravity exists before Newton? yes.But he was searching for answers and that apple gave him the insight.
Do you remember the story about Fleming and the penicillin? Samples get bad every day,Things get rotten every second,and thrown to the garbage.But he was searching for answers.
The soul often whispers to us through synchronistic events. A synchronistic event occurs when we recognize that two or more causally unrelated events resemble each other and catch our attention. For example, you're trying to remember the name of a childhood classmate. In the course of conversation, somebody mentions the very name you had been searching for. Synchronistic events can be a powerful "heads-up", calling us to pay attention.

Another example that many have experienced is the thunderclap that resounds just as we are making some very important statement. Of course, not all synchronistic events are so transparent, and sometimes we do not recognize a synchronistic series until we look back and see all the clues.
