No one is an island...

ACIM has heavy doses of metaphysics and psychology. So much so, one can get bogged down and overlook the stated purpose of the Course.

The Course was refined in the cauldron of interpersonal conflict, specifically, between Bill Thetford and Helen Schucman. It was written as a response to Bill's statement: "There must be a better way." The Course responds "There is and here it is." Everything written after that assists in breaking down barriers we believe separate us from everyone and everything else but which, in reality, are illusory.

There is no separation the Course affirms repeatedly --- not between me and "God," not between me and my brother. The Course affirms that there is no problem between me and God, never was, never will be. The problem exists in the mistaken belief that I'm separated not only from God but also from my brother (that's "the problem" --- ie the belief in separation). When I come to peace with my brother (ie everyone who has been brought into my life), through forgiveness (acceptance) and the atonement (at-one-ment) I then, and only then, experience what the Course calls the "peace of God."

If ever I am to experience peace, in terms of the Course, it has to come through my interpersonal relationships. That's where the Course started. That's where the Course ends. We make it together, you and I.
