This quote is probably most fave out of the book, out of all of them actually, and it is said by Aslan in the end of the book after Edmund had asked if Aslan was also in our world:
"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."
