Once upon a time a sculptor was chipping away at a huge block of marble. Two young children, a boy and a girl, watched him work for many weeks. They stood silently and were amazed when finally a magnificent lion emerged from the stone and stood towering over them. They ran to him excitedly, their eyes wide with wonder and asked: "How did you know that there was a lion hidden in that rock?"
The sculptor laughed and thought to himself, how do I tell them that I had known the lion before I knew the marble stone and what it hid? But he looked at the children and said: "I was very quiet when I first started and listened to the stone and I heard the lion roaring inside. Then I chipped away at everything that wasn't the lion and set him free!" (Rites of Justice, Megan McKenna 1997, Orbis Books).
