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;

Alexander Pope, "Eloisa to Abelard"
English poet & satirist (1688 - 1744)

- speaks to Elosia's desire - and inability - to forget her love for Abelard. She refers to herself as a 'vestal' - a virginal nun, because she has been forced to take orders / vows. She believes that if she were a more faithful nun then she would be able to forget her love, and her lust, and be happy in her confinement.
