"When you stare into the abyss, the abyss stares into you" comes from "Beyond Good and Evil" by the famous German philosopher Friedrich Wilhelm Nietzsche.

The original sentence is: If you fight with the dragon for too long, you will become a dragon yourself; if you stare into the abyss for too long, the abyss will stare back. The meaning of this sentence is: when you fight against the darkness, the darkness is also eroding you.

In the TV series "Eye of the Storm", Bureau Qin used this sentence to remind Ma Shang, who was helpless in the face of the case, not to go crazy, let alone let the suspect influence his mind.

Nietzsche’s classic quotations

1. A more advanced philosopher is alone, not because he wants to be alone, but because he cannot find his kind around him.

2. What doesn’t kill me makes me stronger!

3. People who suffer have no right to be pessimistic. If a suffering person is pessimistic, he will not have the courage to face reality and the strength to fight against suffering. As a result, he will suffer even more.

4. People either never dream, or they have interesting dreams; people must also learn to wake up: either they never wake up, or they have interesting dreams.
