And a voice spoke to the boy, "You shall be the keeper of the Grail, that it may heal the hearts of men."
But the boy was blinded by greater visions, of a life filled with power and glory and beauty. And in this state of radical amazement, he felt for a brief moment not like a boy, but invincible - like God. And so, he reached into the fire to take the Grail...and the Grail vanished, leaving him with his hand in the fire, to be terribly wounded.
Now, as this boy grew older, his wound grew deeper, until one day, life for him lost its reason. He had no faith in any man, not even himself. He couldn't love or feel love. He was sick with experience. He began to die.
One day, a fool wandered into the castle and found the king alone. Being a fool, he was simple-minded; he didn't see a king, he saw a man alone and in pain.
And he asked the king, "What ails you, friend?"
The king replied, "I'm thirsty. I need some water to cool my throat." So the fool took a cup from beside the bed, filled it with water, handed it to the king.
As the king began to drink, he realized that his wound was healed. He looked at his hands, and there was the Holy Grail that which he sought all his life!
And he turned to the fool and said in amazement, "How could you find that which my brightest and bravest could not?"
And the fool replied, "I don't know. I only knew that you were thirsty."
