Are you in pain, Frodo?' said Gandalf quietly as he rode by Frodo's side. 'Well, yes I am,' said Frodo. 'It is my shoulder. The wound aches, and the memory of darkness is heavy on me. It was a year ago today.' 'Alas! there are some wounds that cannot be wholly cured,' said Gandalf. 'I fear it may be so with mine,' said Frodo. 'There is no real going back. Though I may come to the Shire, it will not seem the same; for I shall not be the same. I am wounded with knife, sting, and tooth, and a long burden. Where shall I find rest?' Gandalf did not answer.
J. R. R. TolkienThe Resurrection was the greatest ‘eucatastrophe’ possible in the greatest Fairy Story — and produces that essential emotion: Christian joy which produces tears because it is qualitatively so like sorrow, because it comes from those places where Joy and Sorrow are at one, reconciled, as selfishness and altruism are lost in Love.
