"Whenever you are with a brother you are learning what you are, because you are TEACHING what you are. He will respond either with pain or with joy, depending on which teacher YOU are following. HE will be imprisoned or released according to your decision, AND SO WILL YOU. Never forget your responsibility to him, because it is your responsibility to YOURSELF. Give him HIS place in the Kingdom, and you will have YOURS. The Kingdom CANNOT be found alone, and you who ARE the Kingdom cannot
find YOURSELVES alone.
To achieve the goal of the curriculum, then, you CANNOT listen to the ego. Its purpose is to DEFEAT ITS OWN GOAL. It does not know this, because it does not know anything. But YOU can know this, and you WILL know it if you are willing to look at what the ego has made of YOU. This IS your responsibility, because once you have really done this you WILL accept the Atonement for yourself. What other choice could you make?
Having made this choice, you will begin to learn and understand why you have believed that when you meet someone else, you have thought he WAS someone else. And every holy encounter in which YOU enter fully will teach you THAT THIS IS NOT SO. You can encounter ONLY part of yourself, because you are part of God WHO IS EVERYTHING. His power and glory are everywhere, and you CANNOT be excluded from them. The ego teaches that your strength is in you ALONE. The Holy Spirit teaches that ALL strength is in God and THEREFORE in you."
- Jesus Christ in The Urtext of ACIM, Chapter 8A-F
