Kurama — memorable quote from Yu Yu Hakusho: Ghost Files

“You were wrong on two counts. Even the hardest substance can be broken, when crashed into itself. And the ability to feel pain is not a weakness. It’s a strength. Pain tells a creature its vulnerabilities, and not you expose them to attack. Your robot is dead. And so, I’m afraid, are you.”

“Ant king , you believe I cannot pray with a single arm? A prayer comes from the heart. If the heart achieves the correct form, it becomes emotions and emotions can be manifested.”

“If praying does not work, and words are ineffective... what's left is to fight.”

“Someone who can't see the opponent before them can't see the opponent lying beyond.”

“Don't start a fight if you can't end it.”
