“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”

“In this world, perfection is an illusion. Reagrdless of all those who utter the contrary, this is the reality. Obviously mediocre fools will forever lust for perfection and seek it out. However, what meaning is there in perfection? None. Not a bit. ...After perfection there exists nothing higher. Not even room for creation which means there is no room for wisdom or talent either. Understand? To scientists like ourselves, perfection is despair. - Kurotsuchi Mayuri (Bleach 306)”

“if something is perfect, then there is nothing left,there is no for imagination, no place left for a person to gain additional knowledge or abilities”

“The name sounds almost too perfect. And as I said, you look perfect, too. The only thing left... is to be perfect.”

“‎Imagine that every person in the world is enlightened but you. They are all your teachers, each doing just the right things to help you learn perfect patience, perfect wisdom, perfect compassion.”

“What is Zen? Zen means doing anything perfectly, making mistakes perfectly, being defeated perfectly, hesitating perfectly, doing anything perfectly or imperfectly, perfectly. What is the meaning of this perfectly? How does it differ from perfectly? Perfectly is in the will; perfectly is in the activity. Perfectly means that at each moment of the activity there is no egoism in it… our pain is not only our own pain; it is the pain of the universe. The joy of the universe is also our joy. Our failure and misjudgment is that of nature, which never hopes or despairs, but keeps on trying. R. H. Blyth”

“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.”
