of more worth than all the glory of Valinor and all the grace and beauty of Kor is peace and happiness and wisdom,
But much darker than the snippet I give is the full quote from a speech of Manwë (King of the Valar, called "Gods" in this version). The Noldor from Kor (Tirion) had behaved selfishly and unfriendly to the Valar and each other. Taking advantage of this created sorry state, Melko caused the first death of an elf, the first regicide, and the first orphan.
Without the Gods who brought you to the light
and gave you all the materials of your craft,
teaching your first ignorance,
none of these fair things you love now so well
ever would have been;
what has been done may again be done,
for the power of the Valar does not change;
but of more worth than
all the glory of Valinor and all the grace and beauty of Kor
is peace and happiness and wisdom,
and these once lost
are harder to recapture.
Cease then to murmur and to speak against the Valar,
or to set yourselves in your hearts as equals to their majesty;
rather depart now in penitence
knowing full well that Melko has wrought this evil against you,
and that your secret trafficking with him has brought you all this loss and sorrow.
Trust him not again therefore,
nor any others that whisper secret words of discontent among you,
for its fruit is humiliation and dismay."
While Manwë certainly preaches eloquently, I am simpler spoken:
if you must chose between
your friendship and your stuff,
choose your friends.
They are harder to come by and harder to make
than anything made by hands.
And, when you make that mistake, as we do because we love our stuff,
apologize and atone to your friends and those that helped you.
and turn away from those that lead you astray.
