There is a very old saying in German language, "Hilf Dir selbst dann hilft Dir Gott." (means, make the first step and god will help you with the next steps towards your goals/dreams/wishes) Well, I have my very own view on god, but what I truly believe is that it needs a sharp focus, persistence and that I have to make the first step, so that coincidence can bring some surprises into my life. If the focus is sharp, resonance will then bring most useful information, sometimes support into one's life. But the focus seems to me of huge importance.
Coincidence and Science Fiction, yes, oh how I love Philip K. Dick's writings. He had quite some knowledge and insights ... long time ago I watched a documentary feature about him, very impressive.
I think the concept of coincidence seems not to exist in the Japanese culture - the way we might know it. I somehow believe that "joss" how destiny is called in Japanese culture and "wa" (Japanese for harmony) go hand in hand. This combination of "joss" and "wa" points may be in a right direction ... in a way ...
