- Dumbledore: I suppose, Harry, you are wondering why I brought you here?Harry: Actually, sir, after all these years I just go with it.Dumbledore: I am not worried, Harry, I am with you.Dumbledore: In spite of all the temptation you have endured, all the suffering, you remain pure of heart, just as pure as you were at the age of eleven, when you stared into a mir-ror that reflected your heart's desire, and it showed you only the way to thwart Lord Voldemort, and not immortality or riches. Harry, have you any idea how few wizards could have seen what you saw in that mirror? Voldemort should have known then what he was dealing with, but he did not! But he knows it now. You have flitted into Lord Voldemort's mind without damage to yourself, but he cannot possess you with-out enduring mortal agony, as he discovered in the Ministry. I do not think he understands why, Harry, but then, he was in such a hurry to mutilate his own soul, he never paused to understand the incomparable power of a soul that is untarnished and whole.Prime Minister: But for heaven's sake—you're wizards! You can do magic! Surely you can sort out—well—anything!Minister of Magic: The trouble is, the other side can do magic too, Prime Minister.
