What happened down in the dungeons between you and Professor... - J.K. Rowling, Harry Potter and the Sorcerer's Stone

"One can never have enough socks,"said Dumbledore. "Another Christmas has come and gone and I didn't get a single pair. People will insist on giving me books."

"So light a fire!"Harry choked. "Yes...of course...but there's no wood!"... "HAVE YOU GONE MAD!"Ron bellowed. "ARE YOU A WITCH OR NOT!"

"The truth."Dumbledore sighed. "It is a beautiful and terrible thing, and should therefore be treated with great caution."

"Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. Love as powerful as your mother's for you leaves it's own mark. To have been loved so deeply, even though the person who loved us is gone, will give us some protection forever."

"To the well-organized mind, death is but the next great adventure."
