M-18.1. Correction of a lasting nature,—and only this is true correction,—cannot be made until the teacher of God has ceased to confuse interpretation with fact, or illusion with truth. 2 If he argues with his pupil about a magic thought, attacks it, tries to establish its error or demonstrate its falsity, he is but witnessing to its reality. 3 Depression is then inevitable, for he has "proved," both to his pupil and himself, that it is their task to escape from what is real. 4 And this can only be impossible. 5 Reality is changeless. 6 Magic thoughts are but illusions. 7 Otherwise salvation would be only the same age-old impossible dream in but another form. 8 Yet the dream of salvation has new content. 9 It is not the form alone in which the difference lies.

M-18.2. God's teachers' major lesson is to learn how to react to magic thoughts wholly without anger. 2 Only in this way can they proclaim the truth about themselves. 3 Through them, the Holy Spirit can now speak of the reality of the Son of God. 4 Now He can remind the world of sinlessness, the one unchanged, unchangeable condition of all that God created. 5 Now He can speak the Word of God to listening ears, and bring Christ's vision to eyes that see. 6 Now is He free to teach all minds the truth of what they are, so they will gladly be returned to Him. 7 And now is guilt forgiven, overlooked completely in His sight and in God's Word.

M-18.3. Anger but screeches, "Guilt is real!" 2 Reality is blotted out as this insane belief is taken as replacement for God's Word. 3 The body's eyes now "see"; its ears alone can "hear." 4 Its little space and tiny breath become the measure of reality. 5 And truth becomes diminutive and meaningless. 6 Correction has one answer to all this, and to the world that rests on this:

7 You but mistake interpretation for the truth. 8 And you are wrong. 9 But a mistake is not a sin, nor has reality been taken from its throne by your mistakes. 10 God reigns forever, and His laws alone prevail upon you and upon the world. 11 His Love remains the only thing there is. 12 Fear is illusion, for you are like Him.

M-18.4. In order to heal, it thus becomes essential for the teacher of God to let all his own mistakes be corrected. 2 If he senses even the faintest hint of irritation in himself as he responds to anyone, let him instantly realize that he has made an interpretation that is not true. 3 Then let him turn within to his eternal Guide, and let Him judge what the response should be. 4 So is he healed, and in his healing is his pupil healed with him. 5 The sole responsibility of God's teacher is to accept the Atonement for himself. 6 Atonement means correction, or the undoing of errors. 7 When this has been accomplished, the teacher of God becomes a miracle worker by definition. 8 His sins have been forgiven him, and he no longer condemns himself. 9 How can he then condemn anyone? 10 And who is there whom his forgiveness can fail to heal?
