In "The Magician's Nephew," C.S. Lewis describes a scene in the last chapter where Aslan sends the children, Digory and Polly, back to their own world:
Both the children were looking up into the Lion's face as he spoke these words. And all at once (they never knew exactly how it happened) the face seemed to be a sea of tossing gold in which they were floating, and such a sweetness and power rolled about them and over them and entered into them that they felt they had never really been happy or wise or good, or even alive and awake, before. And the memory of that moment stayed with them always, so that as long as they both lived, if ever they were sad or afraid or angry, the thought of all that golden goodness, and the feeling that it was still there, quite close, just round some corner or behind some door, would come back and make them sure, deep down inside, that all was well.
