If in your relationships you experience both "love" and the opposite of love—attack, emotional violence, and so on—then it is likely that you are confusing ego attachment and addictive clinging with love. You cannot love your partner one moment and attack him or her the next. True love has no opposite. If your "love" has an opposite, then it is not love but a strong ego-need for a more complete and deeper sense of self, a need that the other person temporarily meets. It is the ego's substitute for salvation, and for a short time it almost does feel like salvation.
— Eckhart Tolle
