ACIM: "The Separation HAS occurred. To deny this is merely to misuse denial."
"However, to concentrate on error is merely a further misuse of legitimate psychic mechanisms. The true corrective procedure, which has already been described as the proper use of the spiritual eye (or true vision), is to accept the error temporarily, BUT ONLY as an indication that IMMEDIATE correction is mandatory. This establishes a state of mind in which the Atonement can be accepted without delay."
It's a very common belief that ACIM teaches "separation is impossible". It's the idea that "the separation did not happen". And this also leads to the belief that "I need do nothing" because nothing's really happened. Which then justifies literally "doing nothing" in the presence of "something happening".
The fact remains, that there is a "something" body sitting looking at a screen reading these words on the surface of a physical object. And no matter whether separation "happened" or not, something other than total abstract reality IS occurring right now. You ARE reading this. If it were "the whole story" that "separation did not happen", it would not even be possible to read these words, or for you to even have eyeballs. But it is. And denying that is not helpful. Something is happening here. Or at the very least, SEEMING to.
The distinction that needs to be made is this. REAL separation is not possible. Let's be clear, that you cannot in reality change God or His Creation. "What God has has brought together let no man put asunder" basically means what God creates is permanent. So literally, you cannot create a REAL split in Reality. You can't ACTUALLY cut your REAL self off from the REAL Father.
It is in this sense and only in this sense, that separation is impossible and has not happened. You literally cannot and have not separated. It's the same thing as saying you cannot sin because you cannot cause God. Which means there literally is no REAL sin. Nothing real can be threatened. So we can say, you cannot REALLY separate from God. However, this is not the end of the story.
"Your Father created you wholly without sin, wholly without pain, and wholly without suffering of any kind. If you deny Him, you bring sin, pain, and suffering into your OWN mind, because of the power He gave it. Your mind is capable of creating worlds, but it can also DENY what it creates, because it is free."
While on the one hand you can co-create with God freely, in accord with His will, you CAN also DENY creation, because you HAVE that freedom. This is what "mis-creation" means. You use your freedom to create, against itself, to try to create nothingness. And here is the fact. We DID attempt to do this.
We DID have a tiny mad idea, that it was POSSIBLE to deny creation. Not merely to conceive of mis-creating or denying reality, but that by doing so it would have REAL EFFECTS. By mis-creating or attempting not to create, the result in truth is NOTHING HAPPENS. It's more like you become unwilling and stop willing anything at all, so you don't really do anything.
But you BELIEVE that by denying reality you DO something REAL, which you believe has real consequences or effects. You think that somehow "willing nothing" (death) can be real, and can replace reality. That "not creating" can be considered a "happening". It's because you believe in the mad idea, that you "make it real" to you. And whatever you believe in SEEMS like reality.
You cannot produce a REAL separation, and you haven't. BUT, you can deny reality and TRY to believe that an IMAGINED separation is possible. You can dream of separation. You can invent illusions, which is what it looks like when you repress or withhold extension. You can put the brakes on eternal life, by resisting your own creative power. And this is an attempt to STOP creation. ie, to kill it.
This results in what seems to be a state of death, or a dream of death. "Death is the central dream from which all illusions stem." As the mind denies itself, which imprisons its will, this kind of "puts it to sleep". It is resisting its own wakefulness. This resistance against life seems to take on the form of bodies and forms and sickness and death. These are the "slowing down" of unlimited extension, or the contraction of fear which "materializes" as physical matter. Or as the Course says, "the granite block of sin."
You can believe in this dream and make it seem real to you. You can imagine or mistake this dream for "actual" separation. And therefore can believe that a sin has really occurred. You can look to "events" and believe them, as if proving separation IS happening. But it's not REAL sin or REAL separation that we're trying to fight our way out of, it's an IDEA of it. We're believing that an IMPOSSIBLE separation is possible. And this believing is PRODUCING the world.
This is why Jesus says "The separation HAS occurred." Because He isn't referring to an ACTUAL separation. "The separation", also referred to as "the fall of man", isn't a name for a REAL separation from God. ACIM isn't even dealing with a real separation. But it is dealing with the fact that you DID have an idea of the impossible being possible, and you DID believe in it, and you DID mis-create, and you DID resist and deny reality.
While this "state" is not real separation, it IS a "mis-use" of freedom to create against creation. It has resulted in the "illusory" state of what it looks like to seemingly "not create". Or rather, to use creative power to make it seem like there is no creative power. To use life to pretend there is no life. To use the mind to pretend there is no mind. Even in death, a state of "no choice or will", both choice and will are being fully utilized to make it seem to happen.
"The separation" isn't anything to do with "you actually did separate". It's to do with you ACTUALLY DID DENY reality. You DID conceive of using free will against itself. You DID use your mind to deny your mind, putting it into what seem to be states of unconsciousness (death).
This has resulted in "dreaming", which has resulted in the making of entire illusory worlds, complete with seemingly happening bodies. And yet "all events are nowhere" because they are really a DENIAL of happening. The "occurring" or "happening" is actually a NOT occurring or happening, masquerading as an occurring or happening. This is how it deceives. It SEEMS to be real.
This has thus "made up" (fiction) a world which Jesus refers to as "a lower order reality". It is something you made in an attempt to NOT create anything. It is a NOT world. It is made of NOT bodies. It is the dream of pretending you are not creating anything, and not having eternal life. It's what you get when you use freedom to will against will. THIS illusory mis-creative state DID OCCUR. Mind DID go to sleep a while. It HAS dreamed of a universe made of nothing.
This doesn't mean a real separation has happened. But a fictional separation HAS happened. And so long as we believe it is a "something", rather than an attempt "not to do anything", or "not to live", we are in a state of denial. This denial produces all illusions of suffering and death. Thinking UNREAL things are real, that the world is real, is a mistake. It is a DENIAL OF reality.
"The world was made as a place where God (reality) could enter not".
God wills only to create. He does not ever will to use creation against itself. He does not deny himself or go to sleep. However, creation BY His children is not yet perfected, and so we need help to return to "sanity", which means only using creation constructively.
To be in reality means to not use will against itself, and to not believe that doing so does something. All it does is nothing. Mistaking the nothing for a something is "the fall of man", ie "the separation." Deception, denial, confusion, insanity, and the dream of death.
"The creation of the Soul itself has already been perfectly accomplished, but the creation BY Souls has not. God created Souls so He could depend on them BECAUSE He created them perfectly. He gave them His peace so they would not be shaken, and would be unable to be deceived. Whenever you are afraid, you ARE deceived. Your mind is NOT serving your Soul. "
"Your creation by God is the only foundation which cannot be shaken, because the light is IN it. "
So we ARE in a situation where we're making an illusory world, made of nothing, which seems like a something. And it's not quite a total nothingness otherwise even this would not seem to happen. It has a little amount of reality left in it. Even the ego depends on God a little. But these dreams of opposition to creation are lesser realities, denials of happiness and blocks to awareness. They also deny permanence and eternal life.
So the fact is, we DO need to "do something", given the context of the denial state we are in. Which is why God created the curriculum and the Holy Spirit. Because we DID choose to believe in unreality (the rejection of reality, using reality against itself). We are trying to hold a fake world in place. We, in time, are still choosing the ego.
"I need do nothing" is an atonement-level truth, only LIVED when fully accepted. It means there are no REAL NEEDS. You don't NEED to accomplish something because all that's happened is the ABSENCE of accomplishment. Darkness is the ABSENCE of light.
Even though in reality there are no real needs, your investment in neediness DOES have to be undone. You do need to UNLEARN everything you taught yourself in error. Until there is no more "need" for time and space. The curriculum therefore is aimed to help you to remember that mis-creating against your will is not what you want, and has no merit, or appeal.
It is futile, because you are merely attempting to NOT CREATE anything. The "creation" of death is not creation of anything. Or in other words, "the separation" does not cause anything to happen, has no real consequences, and is pointless. The "sane" would recognize this, and not bother to entertain the notion that "denying creation" is a worthwhile exercise. And in the total withdrawal from trying to make it achieve something real, the world you made disappears.
"The world will spin into the nothingness from which it came."
There has been no real separation.
There has been AN ATTEMPT to make the impossible possible.
You have TRIED to separate from God.
You have used creative will against itself, denying your will to will anything at all.
You mistook the "willing of nothingness" for a "something".
You now seem to NEED atonement. To correct the mistaken belief that willing nothing will produce a SECOND KINGDOM.
Once you accept that ONLY the Kingdom of God accepts its own existence and is in accord with willingness, the world that was NOT created does not exist.
"Heaven remains your one alternative to this strange world you made and all its ways; its shifting patterns and uncertain goals, its painful pleasures and its tragic joys. God made no contradictions. What denies its own existence and attacks itself is not of Him. He did not make two minds, with Heaven as the glad effect of one, and earth the other's sorry outcome which is Heaven's opposite in every way."
There is no world. But you think there is.
