"Are you afraid? You don’t want to die, do you? Not just Abarai, if anyone… acts upon the thought of not wanting you to die, you will suddenly begin to fear your impending death, right?"

"[To Orihime] Your heart? You humans say that word so lightly. As if it were something one can hold in the palm of one's hand. But my eye sees everything -- Nothing can escape it. What it doesn't see doesn't exist. That's how I've always fought. That's how I've always lived."

"Isn't she awfully happy...for someone visiting a grave?"

"[to Szayel Aporro Grantz] Immaculate being... Was it? In this secular existence, perfection is an illusion, regardless of those who utter the contrary. This is the reality. Common man seeks it out, they strive to achieve it, as if it were some tangible thing... But... The fact of the matter is, perfection is a hollow shell. It is devoid of any substance. I spit on perfection. Perfection, after all, implies you've reached the summit. No trial and error, no ability to conceptualize. An omniscient being would have no need for such superfluous things... Am I making myself clear? For people who dabble in the sciences, such as ourselves, perfection would make us obsolete. Many magnificent things have been, and will continue to come into existence... And yet every last one of them will fall short of perfection's finish. Our function as men of science relies on their many shortcomings. Then, and only then, can we apply the fruits of our labor. To put it simply... As soon as you began spouting that nonsense about being an immaculate being... your fate was sealed. How dare you call yourself a man of science?"

"Showing your back in a battle? You've become a fool Yoruichi!"

"Dammit, I'll show you who's more skilled with his language skills!"
