It is a mystery indeed how some people connect with some certain others in a lightening that strikes right through the heart. No wonder such myths as reincarnation and telepathy are abound. I have my own "scientific" (not!) theory --- Perhaps after all there is a limit to the combinations of genetic composition of the brain. Perhaps after billions and billions of randomly generated individual brains year after year and generation after generation, some temperment and structures are inevitably repeated, even if the time, place, and other physical characteristics differ. Thus the sense of deja vu when some come into contact with thoughts and passions that others left and realize that they are gazing into a kindred mind. Thus you penetrate into the heart of your own through someone else's. And this is then the benefit of being artist despite the numerous hazards of this occupation -- you leave a piece of yourself for someone else to pick up, then in this latter person you live again.
Perhaps that is the only opportunity to cast away the ultimate loneliness of being human -- that somewhere across the vast sea of time and space, someone else has a similar molecular blueprint as your own soul.
