"The goal of the curriculum, regardless of the teacher you choose, is “Know thyself.” ²There is nothing else to seek. ³Everyone is looking for himself and for the power and glory he thinks he has lost. ⁴Whenever you are with anyone, you have another opportunity to find them. ⁵Your power and glory are in him because they are yours. ⁶The ego tries to find them in yourself alone, because it does not know where to look. ⁷The Holy Spirit teaches you that if you look only at yourself you cannot find yourself, because that is not what you are. ⁸Whenever you are with a brother, you are learning what you are because you are teaching what you are. ⁹He will respond either with pain or with joy, depending on which teacher you are following. ¹⁰He will be imprisoned or released according to your decision, and so will you. ¹¹Never forget your responsibility to him, because it is your responsibility to yourself. ¹²Give him his place in the Kingdom and you will have yours."
