Books like The Subtle Knife

Let no one rule your mind or body. Take special care that your thoughts remain unfettered, one may be a free man and yet be bound tighter than a slave. Give men your ear, but not your heart. Show respect for those in power, but don’t follow them blindly. Judge with logic and reason, but comment not. Consider none your superior in life. Treat all fairly or they will seek revenge. Be careful with your money. Hold fast to your beliefs and others will listen. Of the affairs of love, my only advice is to be honest. That’s your most powerful tool to unlock a heart or gain forgiveness.

You must not change one thing, one pebble, one grain of sand, until you know what good and evil will follow on that act. The world is in balance, in Equilibrium. A wizard’s power of Changing and Summoning can shake the balance of the world. It is dangerous, that power. It is most perilous. It must follow knowledge, and serve need. To light a candle is to cast a shadow.

Sarai had treasured every stage of Rachel’s childhood, enjoying the day-to-day normalcy of things; a normalcy which she quietly accepted as the best of life. She had always felt that the essence of human experience lay not primarily in the peak experiences, the wedding days and triumphs which stood out in the memory like dates circled in red on old calendars, but, rather, in the unself-conscious flow of little things - the weekend afternoon with each member of the family engaged in his or her own pursuit, their crossings and connections casual, dialogues imminently forgettable, but the sum of such hours creating a synergy which was important and eternal.

I do not aim with my hand;He who aims with his hand has forgotten the face of his father.I aim with my eye. I do not shoot with my hand;He who shoots with his hand has forgotten the face of his father.I shoot with my mind. I do not kill with my gun;He who kills with his gun has forgotten the face of his father.I kill with my heart.

Life is both sad and solemn. We are led into a wonderful world, we meet one another here, greet each other - and wander together for a brief moment. Then we lose each other and disappear as suddenly and unreasonably as we arrived.

Harry couldn’t explain, even to himself, why he didn’t just throw Riddle’s diary away. The fact was that even though he knew the diary was blank, he kept absent-mindedly picking it up and turning the pages, as though it was a story he wanted to finish. And while Harry was sure he had never heard the name T. M. Riddle before, it still seemed to mean something to him, almost as though Riddle was a friend he’d had when he was very small, and half-forgotten. But this was absurd. He’d never had friends before Hogwarts, Dudley had made sure of that.
