C.S. Lewis:
When Aslan said you could never go back to Narnia, he meant the Narnia you were thinking of. But that was not the real Narnia. That had a beginning and an end. It was only a shadow or a copy of the real Narnia: just as our own world, England and all, is only a shadow or copy of something in Aslan’s real world. You need not mourn over Narnia, Lucy. All of the old Narnia that mattered, all the dear creatures, have been drawn into the real Narnia through the Door. And of course it is different; as different as a real thing is from a shadow or as waking life is from a dream ….Your father and mother and all of you are – – as you used to call it in the Shadow-Lands – – dead. The term is over: the holidays have begun. The dream is ended: this is the morning (The Last Battle, 170).
I’m looking forward to it! Revelation 21:3-5, Revelation 22:1-5.
