Mirrors reveal something deep to us — something about ourselves; and it is deep in part because we did not know that it was about ourselves.
By synchronicities we do not mean any old instance of an unlikely event, i.e. one that has a very small probability of occurring. That is necessary, but not sufficient. An event (or circumstance) qualifies as a synchronicity only if it is ‘meaningful’, if it invokes in a subject a sense and feeling of some deeper significance.
