In spiritual maturity, the opposite of injustice is not justice, but compassion. Not me against you, not me straightening out the present ill, fighting to gain a just result for myself and others, but compassion, a life that goes against nothing and fulfills everything.
Compassion is an aspect of Divine love that melts all defenses and resistance when anyone's suffering is really seen. There is nothing the personality can do to create compassion, but when we are willing to be completely open and truthful about whatever we are truly feeling, it arises naturally and soothes our hurt. (We could say that truth without compassion is not really truth, and that compassion without truth is not really compassion.) The Divine love that seeks to express itself in the world through us is a powerful force that can break through all of the old barriers and untruths that have accumulated in us.
