Memory is not what the heart desires.

There was a little corner of his mind that was still his own, and light came through it, as though a chink in the dark: light out of the past. It was actually pleasant, I think, to hear a kindly voice agin, bringing up memories of wind, and trees, and sun on the grass, and such forgotten things.

On two chairs beneath the bole of the tree and canopied by a living bough there sat, side by side, Celeborn and Galadriel. Very tall they were, and the Lady no less tall than the Lord; and they were grave and beautiful. They were clad wholly in white; and the hair of the Lady was of deep gold, and the hair of the Lord Celeborn was of silver long and bright; but no sign of age was upon them, unless it were in the depths of their eyes; for these were keen as lances in the starlight, and yet profound, the wells of deep memory.

Nay! Alas for us all! And for all that walk in the world in these after-days. For such is the way of it: to find and lose, as it seems to those whose boat is on the running stream. But I count you blessed [...] for your loss you suffer of your own free will, and you might have chosen otherwise. But you have not forsaken your companions, and the least reward that you shall have is that the memory of Lothlórien shall remain ever clear and unstained in your heart, and shall neither fade nor grow stale.

Great engines crawled across the field; and in the midst was a huge ram, great as a forest-tree a hundred feet in length, swinging on mighty chains. Long had it been forging in the dark smithies of Mordor, and its hideous head, founded of black steel, was shaped in the likeness of a ravening wolf; on it spells of ruin lay. Grond they named it, in memory of the Hammer of the Underworld of old. Great beasts drew it, orcs surrounded it, and behind walked mountain-trolls to wield it.

Nearly all marriages, even happy ones, are mistakes: in the sense that almost certainly (in a more perfect world, or even with a little more care in this very imperfect one) both partners might be found more suitable mates. But the real soul-mate is the one you are actually married to.

Eastward the dawn rose, ridge behind ridge into the morning, and vanished out of eyesight into guess; it was no more than a glimmer blending with the hem of the sky, but it spoke to them, out of the memory and old tales, of the high and distant mountains.

In sorrow we must go, but not in despair. Behold! we are not bound for ever to the circles of the world, and beyond them is more than memory.
