“He did not know it, but Arwen Undómiel was also there, dwelling again for a time with the kin of her mother. She was little changed, for the mortal years had passed her by, yet her face was more grave, and her laughter now seldom was heard. But Aragorn was grown to full stature of body and mind, and Galadriel bade him cast aside his wayworn raiment, and she clothed him in silver and white, with a cloak of elven-grey and a bright gem on his brow. Then more than any kind of Men he appeared, and seemed rather an Elf-lord from the Isles of the West. And thus it was that Arwen first beheld him again after their long parting; and as he came walking towards her under the trees of Caras Galadhon laden with flowers of gold, her choice was made and her doom appointed.”
― Tolkien, J.R.R

“But Arwen went forth from the House, and the light of her eyes was quenched, and it seemed to her people that she had become cold and grey as nightfall in winter that comes without a star. Then she said farewell to Eldarion, and to her daughters, and to all whom she had loved; and she went out from the city of Minas Tirith and passed away to the land of Lórien, and dwelt there alone under the fading trees until winter came. Galadriel had passed away and Celeborn also was gone, and the land was silent.

'There at last when the mallorn-leaves were falling, but spring had not yet come, she laid herself to rest upon Cerin Amroth; and there is her green grave, until the world is changed, and all the days of her life are utterly forgotten by men that come after, and elanor and niphredil bloom no more east of the Sea.”
― Tolkien, J.R.R

“It is of course perfectly natural to assume that everyone else is having a far more exciting time than you. Human beings, for instance, have a phrase that describes this phenomenon, ‘The other man’s grass is always greener.’
The Shaltanac race of Broopkidren 13 had a similar phrase, but since their planet is somewhat eccentric, botanically speaking, the best they could manage was, ‘The other Shaltanac's joopleberry shrub is always a more mauvy shade of pinky-russet.’ And so the expression soon fell into disuse, and the Shaltanacs had little option but to become terribly happy and contented with their lot, much to the surprise of everyone else in the Galaxy who had not realized that the best way not to be unhappy is not to have a word for it.”
― Douglas Adams, The Hitchhiker's Guide to the Galaxy

“The laws of the universe are never broken. Your mistake is to think that the little regularities we have observed on one planet for a few hundred years are the real unbreakable laws; whereas they are only the remote results which the true laws bring about more often than not; as a kind of accident.”
― C.S. Lewis, That Hideous Strength
