A secret's only a secret as long as you keep it. Once you tell someone it loses all its power -- for good or ill -- like that, it's just another piece of information. But a real mystery can't be solved, not completely. It's always just out of reach, like a light around the corner; you might catch a glimpse of what it reveals, feel its warmth, but you can't know the heart of it, not really. That's what gives it value: It can't be cracked, it's bigger than you and me, bigger than everything we know.
Moving forward in time, it is important that we learn to distinguish between mysteries and secrets. Mysteries precede humankind, envelop us and draw us forward into exploration and wonder. Secrets are the work of humankind, a covert and often insidious way to gather, withhold or impose power. Do not confuse the pursuit of one with the manipulation of the other.
