“When you do find your enemy, remember he will expect and welcome your hate. So surprise him, and let him fear your love.”

“Give your enemy a face, If he is human, do not dehumanize him. Know him and know why he is your enemy. If your enemy is within you, understand what it is and why you are afraid. Put a face on your fear. When you understand it, and it is no longer vague and shapeless, you will find that your fear is no longer so formidable.”

“When you are happy, so happy you have no sense of needing Him, so happy that you are tempted to feel His claims upon you as an interruption, if you remember yourself and turn to Him with gratitude and praise, you will be — or so it feels— welcomed with open arms. But go to Him when your need is desperate, when all other help is vain, and what do you find? A door slammed in your face, and a sound of bolting and double bolting on the inside. After that, silence.”

“You must never call your enemy by a name you choose for him." “Instead you must call him by the name he calls himself. What he chooses will reflect his pride; it will reveal his desires. But what you choose to call him will reveal your fears, which should be kept to yourself, lest your enemy find the way to exploit them.”

“You are determined to hate him [Snape], Harry,” said Lupin with a faint smile. “And I understand; with James as your father, with Sirius as your godfather, you have inherited an old prejudice. By all means tell Dumbledore what you have told Arthur and me, but do not expect him to share your view of the matter; do not even expect him to be surprised by what you tell him. It might have been on Dumbledore’s orders that Severus questioned Draco.”

“You get your freedom by not being confined. You get freedom by letting your enemy know that you'll do anything to get your freedom. You'll get it. It's the only way you'll get it...So dont you run around here trying to make friends with somebody who's depriving you of your rights. They're not your friends. No, they're your enemies. Treat them like that and fight them, and you'll get your freedom. And after you get your freedom, your enemey will respect you. He will respect you. I say that with no hate. I have no hate in me. I don't have any hate, but I've got some sense...I'm not going to let somebody who hates me to tell me to love him. I'm not that way out.”
