A Course in Miracles is a teaching us to leave a dream of mortality, and return to a state of immortality. Everything in the course points to this. You are not merely substituting one limited illusion for another. You are literally substituting DEATH for ETERNAL LIFE. That is why the curriculum culminates in RESURRECTION.
Resurrection is the return to ETERNAL life. The atonement is your acceptance of the fact, that you already have eternal life, eternal life is the only thing true of you, and you have always been immortal. Immortality is your natural state of being. God created you to live FOREVER, without ever suffering, being sick, afraid, dead, or unhappy.
Every single part of ACIM is geared towards you disassociating from illusions of death, vulnerability, victimhood, being affected, being hurt, sickness and all forms of suffering, and re-associating yourself with your IMMORTAL SPIRIT.
As the Course states.
1) You are immortal and you cannot die.
2) You already have eternal life, given by God, and it is permanent.
3) You cannot change your immortality.
4) You are always immortal but when you deny your immortality, you PRETEND to be mortal. You dream of being attackable, suffering and dying, but this has NO EFFECT on your immortality.
5) Those who are sane would never use the dream body to demonstrate SYMBOLS of attack, suffering, sickness or death. To do so is a mixed teaching combining PROOF of belief in attack, with an attempt to teach otherwise. The teaching is only PURE when you are demonstrating the immortality of the body, at least as a SYMBOL of immortality. The body can become a symbol of eternal life, a breath of fresh air to those grown sick of the fetid stench of death.
Life is eternal life. There is no life that is not eternal. This is why there is no life outside of heaven, and life "in the dream world" is an illusion of life.
The entire course is trying to get you to own up to being immortal, invulnerable, completely beyond all forms of attack. You are absolutely permanent. And any time that you ACT as if you are not, as if you have been hurt, affected, caused, damaged, made to suffer against your will, you are LYING, you are in denial, and you are PRETENDING that you are not immortal.
You can see this truth throughout all of ACIM's teachings. e.g.
Deny anything not of God the power to affect you (you cannot BE affected, you are immortal)
Nothing in the world can bring oppression or make you ill or sad or weak or afraid (you cannot be ill or weak or afraid or upset because you are immortal)
There is no cause in the world, it is just an effect (the world cannot cause you in any way because you are unchangeable)
You are not a victim of the world you see (you are incapable of being a victim because you are immortal)
Your attack thoughts are attacking your *invulnerability* (your invulnerability cannot BE attacked because you are immortal, but you can pretend it can)
You cannot be hurt unless you hurt yourself (because you are immortal, and even your hurt of yourself is fake)
You are immortal and cannot die, but you can confuse yourself with things that do (simply, you are immortal)
My self is ruler of the universe. Nothing comes to me unbidden by myself (because you are immortal)
It is your thoughts alone that cause you pain. Nothing external to your mind can hurt or injure you in any way. There is no cause beyond yourself that can reach down and bring oppression. No-one but yourself affects you. (because you are fucking immortal)
It is impossible that anything should come to me unbidden by myself. Even in this world, it is I who rule my destiny. (because nothing can CAUSE YOU, because you are NOT AN EFFECT of anything but God, and you are immortal)
If the mind can heal the body, but the body cannot heal the mind, then the mind must be STRONGER. Every miracle demonstrates this. (because the mind has immortality)
He MUST deny the world of pain, the instant he perceives the arms of love around him. (deny the world because it is an attempt to prove you are not immortal, and its a lie)
This world you see MUST BE DENIED, for sight of it is costing you a different kind of vision. (you must deny all illusions of death, because you are immortal)
Teachers of God choose to look upon dreams a while... they are not deceived by what they see. (because they are immortal and know "death is the CENTRAL ILLUSION from which is all dreams stem" and you cannot die, because you are immortal)
I am not weak but strong. I am not afraid but all powerful. (because you are immortal, nothing has power over you)
YOU ARE IMMORTAL AND YOU CANNOT DIE. And any attempt you are making to PROVE otherwise, is futile and pointless and a form of self deception. When you stop deceiving yourself and others with this denial, you will stop trying to kill yourself, will stop making the body sick or dead, and will OVERCOME DEATH FOREVER.
Immortality is the only truth about you. Ask yourself, why am I trying to prove I am not immortal? Why am I accusing someone of being ABLE to hurt me? Why am I BELIEVING that I have BEEN hurt? Nothing can affect you. It is your own mis-belief that it CAN, that affects you. You hurt yourself, and nothing in the world can cause you suffering of any kind.
Owning up to your immortality is the key to the atonement, the resurrection and the life. THIS is A Course in Miracles. This is the way home to God. Accept your immortality, live by your immortality, demonstrate your immortality, and deny everything else any reality.
Nothing real can be threatened, and YOU ARE REAL. So YOU CANNOT BE THREATENED. Because you are immortal!
So any attempt you make to act as if you are not immortal, to believe someone affected you, something happened to you, something went against your will, you're victimized, you're suffering, etc... it all you PRETENDING TO SUFFER by pretending you are the body, making *IT* suffer, to try to prove that "you" are suffering. Your immortal is unaffected by suffering, sickness and death.
There is no REAL death. The son of God is FREE. But the Son of God can PRETEND to die, by using ILLUSIONS of things that seem to die, to try to prove he is NOT the son of God and not immortal. It's a lie. Do not believe it. Own your immortality and use it to contrast what you are doing that betrays your immortality. Compare your immortality to your victimhood. Can you REALLY have been affected if you have immortality? Can you be justified in TRYING to prove you can suffer?
"Sickness is an attempt to prove you can be hurt". "A damaged body is proof the mind has not been healed." ie if the mind believes it is NOT immortal, it uses the body to TRY to prove that "it" is attackable and vulnerable. And this is always a self deception. You hurt yourself on purpose to try to prove you are not yourself. That has to end in order to accept the atonement and live the resurrection. Your return to ETERNAL LIFE is the goal fo this course.
