When Socrates was asked where he came from, he said that he was a citizen of the world. He regarded himself as a citizen of the universe.
— Marcus Tullius Cicero
When people wanted to kill a bear in the ancient times, they hung a heavy log over a bowl of honey. The bear would push the log away in order to eat the honey. The log would swing back and hit the bear. The bear would become irritated and push the log even harder, and it would return and hit him harder in return. This would continue until the log killed the bear. People behave in the same way when they return evil for the evil they receive from other people. Can't people be wiser than bears?
You should respond with kindness toward evil done to you, and you will destroy in an evil person that pleasure which he derives from evil.
The true teaching of love is strong; it kills evil before evil can grow and become powerful.
