Real love doesn't make you suffer. How could it? It doesn't suddenly turn into hate, nor does real joy turn into pain. As I said, even before you are enlightened—before you have freed yourself from your mind—you may get glimpses of true joy, true love, or of a deep inner peace, still but vibrantly alive. These are aspects of your true nature, which is usually obscured by the mind. Even within a "normal" addictive relationship, there can be moments when the presence of something more genuine, something incorruptible, can be felt. But they will only be glimpses, soon to be covered up again through mind interference. It may then seem that you had something very precious and lost it, or your mind may convince you that it was all an illusion anyway. The truth is that it wasn't an illusion, and you cannot lose it. It is part of your natural state, which can be obscured but can never be destroyed by the mind. Even when the sky is heavily overcast, the sun hasn't disappeared. It's still there on the other side of the clouds.
— Eckhart Tolle
