Sirion just asked:
Also, how does wither sooner refer to being dissatisfied? I don't think you have explained your point clearly enough.
Just for reference, I will repeat the quote under scrutiny:
"And were you so to voyage that escaping all deceits and snares you came indeed to
Aman,
the Blessed Realm, little would it profit you. For it is not the land of
Manwe that makes its people deathless, but the Deathless that dwell therein have hallowed the land; and there you would but wither and grow weary sooner, as moths in a light too strong and steadfast."
Remember this was said by the
Valar's emissaries (I think, did not check that) to the
Númenóreans when they were first murmuring agains the Ban of the Valar (that said that they could not sail so far west that they lose sight of their own island). My point of view is that this is a warning from the emissaries that could be substituted by something like "Do not try to fight your own nature, and become deathless. For there is not any power in the world save that of
Eru Himself that can do anything about it, and the Valar certainly can't help. And if you think that simply living at the same land with the Valar would do you any good, then you are quite mistaken. For
in the company of the deathless your mortality would be even more bitter, and you would be dismayed and rebel against Death with even more anger "
The bold portion is roughly the same in meaning to the sentence "you would but wither and grow weary sooner, as moths in a light too strong and stadefast", as I take it. It is not a literal reading, but it is supported by (a) Aragil's HoME quote that
Men would live "little more than a half-year" (assuming "year" is a translation from the
Quenya yen, which accounts for 144 years of the Sun, so this quote would really mean "little more than 70 years of the Sun", i.e., normal (without the Valar's blessing) human lifespans. And (b) the fact that
Frodo is sent there to heal his wounds. Now is we assume that the "withering" is a literal event, and that Frodo would only "grow weary sooner", his boon (of going to
Valinor) makes no sense, as was pointed out earlier.
This is my interpretation of that quote. I'd be glad to discuss it further if you wish, Sirion.
