“Once a King in Narnia, always a King in Narnia. But don't go trying to use the same route twice. Indeed, don't try to get there at all. It'll happen when you're not looking for it. And don't talk too much about it even among yourselves. And don't mention it to anyone else unless you find that they've had adventures of the same sort themselves. What's that? How will you know? Oh, you'll know all right. Odd things, they say-even their looks-will let the secret out. Keep your eyes open. Bless me, what do they teach them at these schools."-The Professor”
“Once a king or queen of Narnia, always a king or queen of Narnia.”
“This was bad grammar of course, but that is how beavers talk when they are excited; I mean, in Narnia--in our world they usually don't talk at all.- The Lion, The Witch, and the Wardrobe”
“To the glistening eastern sea, I give you Queen Lucy the Valiant. To the great western woods, King Edmund the Just. To the radiant southern sun, Queen Susan the Gentle. And to the clear northern skies, I give you King Peter the Magnificent. Once a king or queen of Narnia, always a king or queen of Narnia. May your wisdom grace us until the stars rain down from the heavens.”
“It is as hard to explain how this sunlit land was different from the old Narnia as it would be to tell you how the fruits of that country taste. Perhaps you will get some idea of it if you think like this. You may have been in a room in which there was a window that looked out on a lovely bay of the sea or a green valley that wound away among mountains. And in the wall of that room opposite to the window there may have been a looking-glass. And as you turned away from the window you suddenly caught sight of that sea or that valley, all over again, in the looking glass. And the sea in the mirror, or the valley in the mirror, were in one sense just the same as the real ones: yet at the same time they were somehow different - deeper, more wonderful, more like places in a story: in a story you have never heard but very much want to know. The difference between the old Narnia and the new Narnia was like that. The new one was a deeper country: every rock and flower and blade of grass looked as if it meant more.”
“But what would have been the good?" Aslan said nothing. "You mean," said Lucy rather faintly, "that it would have turned out all right – somehow? But how? Please, Aslan! Am I not to know?" "To know what would have happened, child?" said Aslan. "No. Nobody is ever told that." "Oh dear," said Lucy. "But anyone can find out what will happen," said Aslan. "If you go back to the others now, and wake them up; and tell them you have seen me again; and that you must all get up at once and follow me – what will happen? There is only one way of finding out.”
“I think you've seen Aslan," said Edmund."Aslan!" said Eustace. "I've heard that name mentioned several times since we joined the Dawn Treader. And I felt - I don't know what - I hated it. But I was hating everything then. And by the way, I'd like to apologise. I'm afraid I've been pretty beastly.""That's all right," said Edmund. "Between ourselves, you haven't been as bad as I was on my first trip to Narnia. You were only an ass, but I was a traitor.""Well, don't tell me about it, then," said Eustace. "But who is Aslan? Do you know him?""Well - he knows me," said Edmund. "He is the great Lion, the son of the Emperor-beyond-the-Sea, who saved me and saved Narnia. We've all seen him. Lucy sees him most often. And it may be Aslan's country we are sailing to.”
