“I know that pain is the most important thing in the universes. Greater than survival, greater than love, greater even than the beauty it brings about. For without pain, there can be no pleasure. Without sadness, there can be no happiness. Without misery there can be no beauty. And without these, life is endless, hopeless, doomed and damned.
Adult. You have become adult.”
― Harlan Ellison, Paingod and Other Delusions

“There is nothing sweeter in this sad world than the sound of someone you love calling your name.”
― Kate DiCamillo, The Tale of Despereaux

“When you light a candle, you also cast a shadow.”
― Ursula K. Le Guin

“Love doesn't just sit there, like a stone, it has to be made, like bread; remade all the time, made new.”
― Ursula K. Le Guin, The Lathe of Heaven
