" God created
the soul pure, simple and clean of all stain of sin, with a certain
beatific instinct towards Himself whence original sin, which the soul finds
in itself, draws it away, and when actual is added to original sin the soul
is drawn yet further away. The further it departs from its beatific
instinct, the more malignant it becomes because it corresponds less to God. "

― Catherine of Genoa , A Treatise on Purgatory
