"Eternal sunshine of the spotless mind" in Ancient Greek

From Eloisa to Abelard by Alexander Pope 207ff:

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;

κεχάρηκεν ἡ ἀμώμη,
τοῦ κόσμου λαθομένη.
ἀεὶ γὰρ ἥλιος ταύτῃ,
πάντα μὲν δεξαμένῃ,
οὐδὲν δὲ ποθουμένῃ.

εὖγ᾽, εὖγε.
