“He who fights too long against dragons becomes a dragon himself; and if you gaze too long into the abyss, the abyss will gaze into you.”
“He who fights with monsters should look to it that he himself does not become a monster . . . when you gaze long into the abyss the abyss also gazes into you”
“Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.”
“Beware that, when fighting monsters, you yourself do not become a monster... for when you gaze long into the abyss. The abyss gazes also into you.”
“And if you gaze for long into an abyss, the abyss gazes also into you.”
“If you gaze long into an abyss, the abyss will gaze back into you?”
