Separation vs The Separation from God

"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."

I thought I'd clarify a bit. In ACIM there are two ways that separation is referred to. One is "separation" in general - the other is "the separation".

Separation in general cannot happen, you cannot never really separate from God, and you haven't. This is what it means by separation being impossible, that "separation hasn't happened."

But you have to be very careful on the wording. ACIM has many references to "THE separation". When it refers to THE separation, it's not talking about the fact that you cannot separate. It's talking about the tiny mad idea which you BELIEVED was possible.

The mad idea is that idea that you CAN separate from God, even though you can't. And believing in the idea is insane, because it makes no sense. Given that the first type of separation - actual separation from God - is utterly impossible, the second variant of separation - the BELIEF THAT IT CAN HAPPEN - still remains possible.

You ARE free to believe things that aren't true if you so wish, and this is what happened when you BELIEVED that you could be separate from God. Even though this belief DID NOT make you separate from God, you still believed that IT DID. And your mind entered a state of sleep and dreaming in which it pretends to be mortal and apart from God, exciled from heaven, even though this is in truth impossible.

That second type of separation, the belief that you can be separate even though you can't, is referred to as "THE separation" in ACIM. It is also referred to as the "fall of man", "the journey into fear", "the descent into hell" etc. It's what happened when you in your mind decided to "listen to the lies of the serpent" and therefore threw your mind into a confused state.

NB: "The separation" shows up on over 45 pages in ACIM and is mentioned close to 90 times.

This second type of separation, HAS in fact happened. The tiny mad idea WAS THOUGHT in the mind. You did HAVE the idea. You also did entertain the idea and put your faith in it, thus believing in it in an attempt to MAKE it be true. You did this because it's NOT true, and although separation is NOT possible, you WANTED it to be possible.

The BELIEF in separation is what THE separation from God is all about, and it is because of this belief - which is a mistaken belief and NOT TRUE, that you find yourself sitting and reading facebook messages. It's why there seems to be a planet under your feet and why you seem to be using a body. All of this came about because of a BELIEF that you COULD be separate from God. And this believing is still ongoing until you reach the atonement.

So in time, we are stuck inside this belief-construct, which ACIM also refers to as "the space-time belief", which houses the cosmos and the galaxies etc. All of this is showing up in your mind as a hallucination because you BELIEVE IN IT. You think it is possible AND happening, and so it SEEMS to be happening. You make it seem real to you because you BELIEVE that separation is possible.

And in this sense, at least a fictional belief that you ARE separate has entered your mind. But this belief is mistaken, in light of the fact that separation is actually impossible. You cannot DENY that you have had this belief, or that you are still having it. You DO believe separation is possible, which is why you are 'here' on planet earth typing on an imaginary keyboard made of separate keys.

This is why ACIM itself DOES state clearly twice, that "THE separation has occurred." But also teaches that separation IN GENERAL is impossible, and therefore THE separation that's happened is a mistaken thought in the mind. The belief that you can separate has to be undone, but this does NOT mean that you HAVEN'T believed it. "THE separation" has happened (or has seemed to), but general separation has not.
