I cannot express it; but surely you and everybody have a notion that there is or should be an existence of yours beyond you. What were the use of my creation, if I were entirely contained here?

My love for Heathcliff resembles the eternal rocks beneath: a source of little visible delight, but necessary. Nelly, I am Heathcliff! He's always, always in my mind: not as a pleasure, any more than I am always a pleasure to myself, but as my own being.
