A rabbi I know once brought a nursery school class into the synagogue sanctuary for a tour. He showed them the bima, the ner tamid, the cantor"s and rabbi's lecterns. Finally, the tiny kids stood before the huge doors of the Holy Ark.
"What do you suppose is in there?" he asked them.
"Nothing!" one child answered, "It's empty. There’s nothing in there."
"It’s a new car!" another shouted.
"An old, old Torah!" responded another.
"I know! I know" one child insisted, "It's a mirror!"
Each of the kids was right.
