Knowing reality as it is really meant to be is possible only in snatches in this world. From time to time we experience a real meeting with another, a real relationship between equals, and we know that this experience of joy and love is as life is designed to be. The Course says that we would weep if we truly realized how different what we know now is from what we knew in Heaven (T-21.I.7:2) before we drifted into insanity and therefore into illusion.
I believe that God created karma in order to allow us to realize that our way could not work, that only a relationship of oneness with our true Mind, which is at home in God alone, could be reality. Jesus indicates that after much pain we must come to see that there is a better way, and make amends accordingly. If this seems like a dirty trick, that pain is what God visits on us to throw us back on Him alone, then we are misperceiving the truth of reality. Only God’s way can work; anything else proceeds from an illusory cause and brings effects that we would not want. Only in harmony can we live together in this universe. Only in Oneness could the universe survive. The “cause,” the ego, is a false notion of self, and it believes many things that are quite chaotic. This chaos brings on conflict and agony, for what else could transpire?
With karma, we see the boom-a-rang of what we have done to others coming back to ourselves; this is one way of learning. But it is not the only way. With the appearance of Jesus 2,000 years ago, he brought in the Age of Grace–the time in which we can, through meditation, prayer, and reflection, see the error of our ways, and make restitution that does not mean an eye for an eye, a tooth for a tooth. Certainly the Course carries this doctrine a step farther along to real Peace.
