10. The calm being of God's Kingdom, which in your sane mind is perfectly conscious, is ruthlessly banished from the part of the mind the ego rules. The ego is desperate because it opposes literally invincible odds, whether you are asleep or awake. Consider how much vigilance you have been willing to exert to protect your ego, and how little to protect your right mind. Who but the insane would undertake to believe what is not true, and then protect this belief at the cost of the truth?
1. If you cannot hear the Voice for God, it is because you do not choose to listen. That you do listen to the voice of your ego is demonstrated by your attitudes, your feelings and your behavior. Yet this is what you want. This is what you are fighting to keep, and what you are vigilant to save. Your mind is filled with schemes to save the face of your ego, and you do not seek the face of Christ. The glass in which the ego seeks to see its face is dark indeed. How can it maintain the trick of its existence except with mirrors? But where you look to find yourself is up to you.
