“To love at all is to be vulnerable. Love anything and your heart will be wrung and possibly broken. If you want to make sure of keeping it intact you must give it to no one, not even an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements. Lock it up safe in the casket or coffin of your selfishness. But in that casket, safe, dark, motionless, airless, it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. To love is to be vulnerable.”
― C.S. Lewis, The Four Loves

“The opposite of love is not hate, it's indifference. The opposite of art is not ugliness, it's indifference. The opposite of faith is not heresy, it's indifference. And the opposite of life is not death, it's indifference.”
― Elie Wiesel

“I have found the paradox, that if you love until it hurts, there can be no more hurt, only more love.”
― Daphne Rae, Love Until It Hurts: The Work of Mother Teresa and Her Missionaries of Charity

“Love is that condition in which the happiness of another person is essential to your own.”
― Robert A. Heinlein, Stranger in a Strange Land
