“But how can it be？” said Peter. “For Aslan told us older ones that we should never return to Narnia， and here we are.”
“Yes，” said Eustace. “And we saw it all destroyed and the sun put out.”
“And it’s all so different，” said Lucy.
“The Eagle is right，” said the Lord Digory. “Listen， Peter. 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 which has always been here and always will be here： just as our 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.”
