Quote from A Course in Miracles Text Chapter 15 - THE HOLY INSTANT.

T-15.VII.9. Suffering and sacrifice are the gifts with which the ego would "bless" all unions. 2 And those who are united at its altar accept suffering and sacrifice as the price of union. 3 In their angry alliances, born of the fear of loneliness and yet dedicated to the continuance of loneliness, each seeks relief from guilt by increasing it in the other. 4 For each believes that this decreases guilt in him. 5 The other seems always to be attacking and wounding him, perhaps in little ways, perhaps "unconsciously," yet never without demand of sacrifice. 6 The fury of those joined at the ego's altar far exceeds your awareness of it. 7 For what the ego really wants you do not realize.
