Tolkein on Heaven

From his poem in defense of myth, "Mythopoeia" (To one [C.S. Lewis] who said that myths were lies and therefore worthless, even though 'breathed through silver'.):

In Paradise perchance the eye may stray
from gazing upon everlasting Day
to see the day illumined, and renew
from mirrored truth the likeness of the True.
Then looking on the Blessed Land 'twill see
that all is as it is, and yet made free:
Salvation changes not, nor yet destroys,
garden nor gardener, children nor their toys.
Evil it will not see, for evil lies
not in God's picture but in crooked eyes,
not in the source but in malicious choice,
and not in sound but in the tuneless voice.
In Paradise they look no more awry;
and though they make anew, they make no lie.
Be sure they still will make, not being dead,
and poets shall have flames upon their head,
and harps whereon their faultless fingers fall:
there each shall choose for ever from the All.

I like the line, "and poets shall have flames upon their head." I also like the idea that heaven doesn't wipe out the things that were pointing toward it, and the idea that people continue to create in heaven.
