[…] As the sun rose the sight of those mountains outside the world faded away. The wave remained but there was only blue sky behind it.
The children got out of the boat and waded - not towards the wave but southward with the wall of water on their left. They could not have told you why they did this; it was their fate. And though they had felt - and been very grown-up on the Dawn Treader, they now felt just the opposite and held hands as they waded through the lilies. They never felt tired. The water was warm and all the time it got shallower. At last they were on dry sand, and then on grass - a huge plain of very fine short grass, almost level with the Silver Sea and spreading in every direction without so much as a molehill.
And of course, as it always does in a perfectly flat place without trees, it looked as if the sky came down to meet the grass in front of them. But as they went on they got the strangest impression that here at last the sky did really come down and join the earth - a blue wall, very bright, but real and solid: more like glass than anything else. And soon they were quite sure of it. It was very near now.
But between them and the foot of the sky there was something so white on the green grass that even with their eagles’ eyes they could hardly look at it. They came on and saw that it was a Lamb.
“Come and have breakfast,” said the Lamb in its sweet milky voice.
Then they noticed for the first time that there was a fire lit on the grass and fish roasting on it. They sat down and ate the fish, hungry now for the first time for many days. And it was the most delicious food they had ever tasted.
“Please, Lamb,” said Lucy, “is this the way to Aslan’s country?”
“Not for you,” said the Lamb. “For you the door into Aslan’s country is from your own world.”
“What!” said Edmund. “Is there a way into Aslan’s country from our world too?”
“There is a way into my country from all the worlds,” said the Lamb; but as he spoke his snowy white flushed into tawny gold and his size changed and he was Aslan himself, towering above them and scattering light from his mane.
“Oh, Aslan,” said Lucy. “Will you tell us how to get into your country from our world?”
“I shall be telling you all the time,” said Aslan. “But I will not tell you how long or short the way will be; only that it lies across a river. But do not fear that, for I am the great Bridge Builder. And now come; I will open the door in the sky and send you to your own land.”
“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 balk 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 Edmund.
“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.” […]
