Be mindful of what you want to learn. A Course In Miracles teaches a curriculum that we all must learn sooner or later which is about the unconditional love of God. There are many ways to learn this; ACIM is only one. There are many roads to Rome and many ways to skin the cat. Having investigated many paths to learning the unconditional love of God, ACIM, for me, seems to be the best supplemented by others.
If you believe in lies you are not free.
