Reincarnation

[Nukapei]

This is something I have often wondered, too. And having access only to The Hobbit, LotR, and the Sil, it's not something I've been able to rightly answer! I hope it's okay to continue this discusson . . .

So, does this mean that all Elves are reincarnated? The way you worded this makes it sound like the Valar only do this some of the time! And if so, are they reincarned into Valinore? What happens after The Undying Lands fill with reincarned Elves? Does anyone know this, or is it just something Tolkien never touched on?
