A relative passage from ACIM. T-2. VI. 2. I do not foster level confusion, but you must choose to correct it. You would not excuse insane behavior on your part by saying you could not help it. Why should you condone insane thinking? There is a confusion here that you would do well to look at clearly. You may believe that you are responsible for what you do, but not for what you think. The truth is that you are responsible for what you think, because it is only at this level that you can exercise choice.
