All the world's a stage, an act, in which you play your part. But it is just a movie, not real. You give it all the meaning it has for you. You can apply these lessons to the symbols of the world and undo your ego beliefs: "I am never upset for the reason I think." (ACIM, W-5) "I am upset because I see something that's not there." (ACIM, W-6) "I see only the past." (ACIM, W-7) "My mind is preoccupied with past thoughts." (ACIM, W-8) You are trying to maintain a false identity . . .
