“Before facing you enemy, you must first face yourself.”

“Rukia, let me ask you something. From your experience where do you think your heart is?" "um well if I had to guess I think somewhere around here isn't that right?" "If you want to be literal about it. But in my opinion it's more a state of mind. I believe its right here, not inside our bodies at all. I think a heart is created between people when they meet for the first time, a bond that's brought to life between individuals. It's an emotional connection, when you think about something or care about someone, that's where your heart is born. If you were the only person that existed in this world, your heart would have no way of forming so it just wouldn't be anywhere. There's nothing to worry about Rukia. If you believe with all of your heart that you belong here, then this is where you'll stay. If your heart is here then that's all the reason in the world you need to be here. You must never doubt that. But listen Rukia, in the fights to come, there's something I must warn you about. Something you must promise me you will never ever do. I mean this. You must never die alone. Our souls are our bodies and when we die our bodies turn to dust and become the reishi that go on to form the soul society, but where do our hearts go? We entrust our hearts to our friends. If you entrust your heart to your friends it will continue to live on inside them. That's the most important thing you'll learn from my training. Don't you dare die alone Rukia.”

“Do you know why the big brother is born first? It’s to protect the little brothers and sisters that come after him. A brother telling his sister, "I’ll kill you"... You never, ever say something like that.”

“Never admit defeat and ask for a quick death! Die first, then admit defeat! If you are defeated but didn't die, it just means you were lucky! At those times, think only about survival! Survive and think only about killing the one who failed to kill you!~Kenpachi Zaraki”

“The perfect being, huh? There is no such thing as perfect in this world. That may sound cliché, but it’s the truth. The average person admires perfection and seeks to obtain it. But, what’s the point of achieving perfection? There is none. Nothing. Not a single thing. I loathe perfection! If something is perfect, then there is nothing left. There is no room for imagination. No place left for a person to gain additional knowledge or abilities. Do you know what that means? For scientists such as ourselves, perfection only brings despair. It is our job to create things more wonderful than anything before them, but never to obtain perfection. A scientist must be a person who finds ecstasy while suffering from that antimony. In short, the moment that foolishness left your mouth and reached my ears, you had already lost. Of course, that’s assuming you are a scientist”

“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)”

“Sanity? Sorry, I don't ever remember having something like that before.”
