“Can you think what the Mirror of Erised shows us all?" Harry shook his head.

"Let me explain. The happiest man on earth would be able to use the Mirror of Erised like a normal mirror, that is, he would look into it and see himself exactly as he is. Does that help."
Harry thought. Then he said slowly, "It shows us what we want... whatever we want..."
"Yes and no," said Dumbledore quietly.
"It shows us nothing more or less than the deepest, most desperate desire of our hearts. You, who have never known your family, see them standing around you. Ronald Weasley, who has always been overshadowed by his brothers, sees himself standing alone, the best of all of them. However, this mirror will give us neither knowledge or truth. Men have wasted away before it, entranced by what they have seen, or been driven mad, not knowing if what it shows is real or even possible.

"The Mirror will be moved to a new home tomorrow, Harry, and I ask you not to go looking for it again. If you ever do run across it, you will now be prepared. It does not do to dwell on dreams and forget to live, remember that. Now, why don't you put that admirable cloak back on and get off to bed.”
― J.K. Rowling, Harry Potter and the Sorcerer's Stone

“This is our skin and nobody has the right to crumple us like a paper only to find another skin to write on, and then another, ruining people like they’re pages, like they are somehow replaceable. Because that will only leave our delicate and fragile selves into a tattered mess.”
― Heema Shirvaikar

“And I realized that there's a big difference between deciding to leave and knowing where to go.”
― Robyn Schneider, The Beginning of Everything

“No matter how much time passes, no matter what takes place in the interim, there are some things we can never assign to oblivion, memories we can never rub away.”
― Haruki Murakami, Kafka on the Shore
