“In the end, it mattered not that you could not close your mind. It was your heart that saved you.”
“If he doesn't stop trying to save your life he's going to kill you.”
“It was strange how your brain could know what your heart refused to accept.”
“And that's the second time we've saved your life tonight, you two-faced bastard!' Ron yelled.”
“Do you see, Harry? Do you see the flaw in my brilliant plan now? I had fallen into the trap I had foreseen, that I had told myself I could avoid, that I must avoid.”“I don’t —”“I cared about you too much,” said Dumbledore simply. “I cared more for your happiness than your knowing the truth, more for your peace of mind than my plan, more for your life than the lives that might be lost if the plan failed. In other words, I acted exactly as Voldemort expects we fools who love to act.“Is there a defense? I defy anyone who has watched you as I have — and I have watched you more closely than you can have imagined — not to want to save you more pain than you had already suffered. What did I care if numbers of nameless and faceless people and creatures were slaughtered in the vague future, if in the here and now you were alive, and well, and happy? I never dreamed that I would have such a person on my hands.”
“So Dobby stopped us from getting on the train and broke your arm. . . ." He shook his head. "You know what, Harry? If he doesn't stop trying to save your life he's going to kill you.”
“Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. He didn't realize that love as powerful as your mother's for you leaves its own mark. Not a scar, no visible sign… to have been loved so deeply, even though the person who loved us is gone, will give us some protection forever. It is in your very own skin. Quirrel, full of hatred, greed, and ambition, sharing his soul with Voldemort, could not touch you for this reason. It was agony to touch a person marked by something so good.”
