“I don't think jealousy has much of a connection with real, objective conditions. Like if you're fortunate you're not jealous, but if life hasn't blessed you, you are jealous. Jealousy doesn't work that way. It's more like a tumor secretly growing inside us that gets bigger and bigger, beyond all reason. Even if you find out it's there, there's nothing you can do to stop it.”

“But you know you're sounding like a jealous wife? Are you jealous, luv? I find that rather amusing, all things considered.""Don't start laughing too soon, because I'm nothing of the sort.""No?"He was still grinning, prompting her to snap, "Your unexpected presence here smacks of jealousy as well, as in checking up on your wife, but you don't hear me accusing you of it.""I believe you just did.”

When however you love in the most abysmal and unutterable way of all – whey then you’re beyond everything, and nothing can pull you down.”

“What sort of love is permeated by jealousy? You are jealous because you are unaware that everything you need is inside you.”

“There is so much darkness in Ember, Lina. It's not just outside, it's inside us, too. Everyone has some darkness inside. It's like a hungry creature. It wants and wants and wants with a terrible power. And the more you give it, the bigger and hungrier it gets.”
