In the first book of the Harry Potter series, "Harry Potter and the Philosopher's Stone" (or "Harry Potter and the Sorcerer's Stone" in the United States), Harry Potter sees his deceased parents, James and Lily Potter, standing together and smiling at him in the Mirror of Erised. The Mirror of Erised shows a person's deepest, most desperate desire or longing. For Harry, who was orphaned as a baby and grew up without his parents, seeing them alive and happy in the mirror was a profound and emotional experience.
