Aslan’s World

“Please, Aslan,” said Lucy. “Before we go, will you tell us when we can come back to Narnia again? Please. And oh, do, do, do make it soon.”
“Dearest,” said Aslan very gently, “you and your brother will never come back to Narnia.”
“Oh, Aslan!” said Edmund and Lucy both together in despairing voices.
“You are too old, children,” said Aslan, “and you must begin to come close to your own world now.”
“It isn’t Narnia, you know,” sobbed Lucy. “It’s you. We shan’t meet you there. And how can we live never meeting you?”
“But you shall meet me, dear one,” said Aslan.
“Are—are you there too, Sir?” said Edmond.
“I am,” said Aslan. “But there I have another name. You must learn to know me by that name. This was the very reason why you were brought to Narnia, that by knowing me here for a little, you may know me better there.”
