If you focus your awareness only upon your own rightness, then you invite the forces of opposition to overwhelm you.
Frank Herbert. . . is to attempt seeing Truth without knowing Falsehood. It is the attempt to see the Light without knowing Darkness. It cannot be.
Frank HerbertWhen your opponent fears you, then's the moment when you give the fear its own rein, give it the time to work on him. Let it become terror. The terrified man fights himself. Eventually, he attacks in desperation. That is the most dangerous moment, but the terrified man can be trusted usually to make a fatal mistake. You are being trained here to detect these mistakes and use them.
