A Course in Miracles – Chapter 11 – VII. The Condition of Reality
T-11.VII.1. The world as you perceive it cannot have been created by the Father, for the world is not as you see it. 2 God created only the eternal, and everything you see is perishable. 3 Therefore, there must be another world that you do not see. 4 The Bible speaks of a new Heaven and a new earth, yet this cannot be literally true, for the eternal are not re-created. 5 To perceive anew is merely to perceive again, implying that before, or in the interval between, you were not perceiving at all. 6 What, then, is the world that awaits your perception when you see it?
T-11.VII.2. Every loving thought that the Son of God ever had is eternal. 2 The loving thoughts his mind perceives in this world are the world's only reality. 3 They are still perceptions, because he still believes that he is separate. 4 Yet they are eternal because they are loving. 5 And being loving they are like the Father, and therefore cannot die. 6 The real world can actually be perceived. 7 All that is necessary is a willingness to perceive nothing else. 8 For if you perceive both good and evil, you are accepting both the false and the true and making no distinction between them.
T-11.VII.3. The ego may see some good, but never only good. 2 That is why its perceptions are so variable. 3 It does not reject goodness entirely, for that you could not accept. 4 But it always adds something that is not real to the real, thus confusing illusion and reality. 5 For perceptions cannot be partly true. 6 If you believe in truth and illusion, you cannot tell which is true. 7 To establish your personal autonomy you tried to create unlike your Father, believing that what you made is capable of being unlike Him. 8 Yet everything true is like Him. 9 Perceiving only the real world will lead you to the real Heaven, because it will make you capable of understanding it.
T-11.VII.4. The perception of goodness is not knowledge, but the denial of the opposite of goodness enables you to recognize a condition in which opposites do not exist. 2 And this is the condition of knowledge. 3 Without this awareness you have not met its conditions, and until you do you will not know it is yours already. 4 You have made many ideas that you have placed between yourself and your Creator, and these beliefs are the world as you perceive it. 5 Truth is not absent here, but it is obscure. 6 You do not know the difference between what you have made and what God created, and so you do not know the difference between what you have made and what you have created. 7 To believe that you can perceive the real world is to believe that you can know yourself. 8 You can know God because it is His Will to be known. 9 The real world is all that the Holy Spirit has saved for you out of what you have made, and to perceive only this is salvation, because it is the recognition that reality is only what is true.
