“I'm so disappointed, Ichigo, so very disappointed. Sadly, your sword exhibits only fear. When you counter, it's because you fear being killed. When you attack, you fear killing. And when you protect someone, you fear you could let them die. At this point, the only thing your sword speaks is sensless fright, and that's not good. What you don't need in battle is fear. Nothing will come of it. When you counter, you don't let them cut you. When you protect someone, you don't let them die. And when you attack, you kill." -Kisuke Urahara (Bleach)”
