Eternal Sunshine of the Spotless Mind

[natnedanswer]

In the film Eternal Sunshine what is the quote that Kirtsten Dunst's character uses including the words '...eternal sunshine of the spotless mind...'?

She is saying this to the character Howard whilst Joel (Jim Carey) is led on the bed.

If any1 knows the full quote can you please help me.

How happy is the blameless vestal's lot!
The world forgetting, by the world forgot
Eternal sunshine of the spotless mind!
Each pray'r accepted, and each wish resign'd;

From the poem 'From Eloisa to Abelard' by Alexander Pope. I am keeping my fingers crossed that this link will turn blue when I post it so that you can click on it. The line 'Eternal sunshine . . .' is line 209.
