Peace - Words used in A Course in Miracles.

The first obstacle that peace must flow across is your desire to get rid of it. For it cannot extend unless you keep it. You are the center from which it radiates outward, to call the others in. You are its home; its tranquil dwelling place from which it gently reaches out, but never leaving you.             T-19.IV.A.1:1-4.

Peace could no more depart from you than from God. Fear not this little obstacle. It cannot contain the Will of God. Peace will flow across it, and join you without hindrance. .... The little wall will fall away so quietly beneath the wings of peace. For peace will send its messengers from you to all the world, and barriers will fall away before their coming as easily as those that you interpose will be surmounted.   T-19.IV.A.4:3-6,11,12.
 
Every response to the ego is a call to war, and war does deprive you of peace. Yet in this war there is no opponent. ... Those whom you perceive as opponents are part of your peace, which you are giving up by attacking them. … When you give up peace, you are excluding yourself from it.   T-8.I.3:1,2,4,7.
 
If you want peace you must abandon the teacher of attack. The Teacher of peace will never abandon you. You can desert Him but He will never reciprocate, for His faith in you is His understanding. ... With your perfection ever in His sight, He gives the gift of peace to everyone who perceives the need for peace, and who would have it. Make way for peace, and it will come. For understanding is in you, and from it peace must come.   T-14.II.14:1-3,6-8.

...the stage of real peace, for here is Heaven's state fully reflected. … Who would "go" anywhere, if peace of mind is already complete? And who would seek to change tranquility for something more desirable? What could be more desirable than this?   M-4.I.A.8:5,,8-10.
