What is SYNCHRONICITY ?

First, let's give some definitions of the word synchronicity. You can start from the explanation of this term found on the invaluable Wikipedia.
Or you can ask for help defining the term using Google: you'll of course stumble upon some links referring to the famous (and very nice) album by The Police, but you won't probably see another good Web page about synchronicity, the one on Crystalinks or the interesting article on the Delight of Synchronicity site, where is widely promoted one of the very good books I'm going to present in this blog, The Power of Flow, available on Amazon UK (also available on Amazon USA).
Aniway, the definition mostly used for synchronicity is the one I also prefer: a meaningful coincidence that has a low probability of being a random or chance event.
