There are two kinds of secrets in the world, make-believe secrets and real secrets.
A make-believe secret is one that depends on its concealment.
It is shrouded in mystery.
Such a secret relies on darkness and the unknown.
So long as it remains hidden, it arouses interest, but when it is revealed, the mystery vanishes and the secret loses its fascination.
Such is the secret of the trickster and the charlatan, the stage magician and the mystigogue.
Their spell lies in the undisclosed, the mysterious wrapping.
When the inner content or the trick becomes apparent, the magic disappears.
Such is not the case with a real secret.
A real secret can be open and apparent to everyone.
All can see the matter clearly and examine it from all sides.
Nevertheless, the more it is looked at and examined, the more of a secret it becomes, profound and insoluble.
