Abyss

He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you.

Chance

Die Leugner des Zufalls. — 'Kein Sieger glaubt an den Zufall.' (Those who deny chance. — 'No victor believes in chance.')

Love

Was aus Liebe getan wird, geschieht immer jenseits von Gut und Böse. (What is done out of love always takes place beyond good and evil.)
