And pleasure dimmed by longing,
For it was then an evil genius
Began to pay me secret visits.
Our meetings were quite dolorous:
His smile, his glance mysterious,
His venom-filled and caustic sermons
Poured frozen poison in my soul.” —Russian poet Alexander Pushkin (1799-1837), from “The Demons," in Poems Bewitched and Haunted (Everyman's Library) (2005)
