There was a feeling, not sudden, but complete, as though I had been given a small object to hold unseen in my hands. Precious as opal, smooth as jade, weighty as a river stone, more fragile than a bird's egg. Infinitely still, live as the root of Creation. Not a gift, but a trust. Fiercely to cherish, softly to guard. The words spoke themselves and disappeared into the groined shadows of the roof.
