You have to forgive this reality for being different than you have always imagined it to be. You have to forgive yourself for not being able to make it on your own, because you have realized the impossibility of doing so. You have to forgive yourself for being what you are, a being who exists only in relationship. (ACOL, C:6.2)
We are beings meant to live in relationship to each other. A holy relationship that features love as its predominant feature.
We have tried, and failed, to be independent, autonomous, needing nobody and nothing. When we failed at that, we reached for a special someone who would answer all of our needs. And we failed at that, too.
Now forgiveness is in store, for ourselves and our God. Our ego got it wrong, believing that autonomy was the way to go. We are made for each other, interdependently. If we stop and think, we realize this even on a secular level.
Our society thrives on competition, but this competition, bottom line, means that there is somebody else who is very, very important to us. The few among us who recognize that cooperation gets us farther in the long run are surely coming to see that we need each other. And not only for love. We need each other simply to exist side-by-side in our crowded world.
