Here they are:

This is probably my most favourite passage in all the books. I have many favourites (too many for them to be called "favourites"... ), but this sentence is simply unbeatable.

Wait... there's more...

Here ends the SILMARILLION. If it has passed from the high and beautiful to darkness and ruin, that was of old the fate of Arda Marred; and if any change shall come and the Marring be amended, Manwe and Varda may know; but they have not revealed it, and it is not declared in the dooms of Mandos.

This does indeed summarise the whole Sil.
