It is any form of DENIAL, which actually PREVENTS you from being consciously aware of something that has been repressed.

That means that while the block remains, it is not merely a matter of you having to deal with "what you believe" consciously, it's actually about how you are USING this belief in order to HIDE something else that is OUTSIDE of your conscious awareness. Something that you DO NOT BELIEVE IS THERE.

You implemented the block by covering it over with something. This made the thing UNCONSCIOUS to you. Therefore you do not think it exists. You then think that you are in a state of FULL AWARENESS, and that if you do not SEE or are not aware of something in you, it does NOT EXIST. But this is not true.

The block to awareness has MADE the problem unconscious, outside of your awareness, and so you do NOT see it and do not therefore FIND it when you look around you. Thus you think it is not there.

This is why buried underneath DENIAL, there is stuff like unconscious guilt and unconscious sin, lurking in the depths of darkness or unawareness, blocked from sight on purpose, so that you will KEEP IT and not undo it.

Literally, "out of sight, out of mind." or "Swept under the carpet".

This is why fixing blocks to awareness is NOT just the taking back of projections. Projections are just displacements of material, usually coming FROM the unconscious content, but experienced consciously as external or separate from you. That's what the denial MADE HAPPEN.

The block to awareness ITSELF *IS* the layer of denial which has MADE the problem unconscious to you. Everything which supports that denial KEEPS the problem in the dark and beyond your ability to be conscious of it. Blocks of denial must be questioned and undone to REVEAL the unconscious hidden hates and secret sins, otherwise you are dealing only with what you THINK are the problems in your mind while simultaneously AVOIDING the deeper problems you did not want to look at. It was by not wanting to look at the problem that you MADE it unconscious so that you could PRETEND it is not there.

Blocks to awareness LITERALLY BLOCK AWARENESS. Until they are removed, AWARENESS has not been increased. But once they are removed, awareness HAS increased, and you have woken up to more of what you are.

There are two approaches to ACIM. One is to learn the theory about what is true or false. The other is to actually change your mind and transform your awareness so that you wake up to experiencing it.

Theory is learned on a horizontal level. It involves the intellect. It involves trying to understand what ACIM says and means. It's analytical and it studies the words, the levels, the structures, the relationships of things, the definitions of words and the "description" of the truth. it dwells on the form and the word choices and so on.

Some people have an easier time learning the theory than others. Some people are not as intellectually able to get their heads around the intricate depths and nuances of Jesus's genius. For some the theory seems complex and off-putting. And many people get the theory profoundly wrong, while others are very accurate in their discernment of it.

Sometimes there are debates and fights about what the course says and means. This is all to do with the horizontal approach. It's an intellectual battle in which sides try to convince each other that their understanding of the course is the correct one. And in many cases some people may well be correct while others are very lost. There are some people who are so incredibly lost on the theoretical level that they are practically learning a totally different belief system. They think they're heading toward reality while heading away from it.

Then there is a vertical movement away from hell toward heaven, away from darkness toward light, away from ego towards the Holy Spirit, away from the body towards the soul, and away from the world towards the Kingdom of God. This is a transformational movement which does actually require a vertical change of mind, an awakening, a willingness, an opening, and a trust.

In the vertical learning we actually have to apply the theory. The mind has to be transformed. Beliefs have to be undone. Healing has to take place. Your life and your curriculum presents you with challenges and lessons which you have to learn. Your relationships have to change and your sense of identity has to alter. This is not achieved through theory.

Some people struggle to accurately understand the course's theories on the horizontal level, and turn a blind eye to this fact by trying to focus on something more experiential. They may focus on love or feeling. This can produce progress upwards to some extent, but then the faults in the theory hold them back.

It can hold them back such as, for example, someone believing that Earth is God's Kingdom, which is going to pull the person in the completely wrong direction. So while they're trying to go up, faults in the theory are pulling them down. It's like a handicap. There are some quite loving-seeming people doing ACIM who nevertheless say things which are profoundly wrong and delusional.

On the flip side, there are also people who become expert at the horizontal theory. Great intellects and scholars and theologians who are very good at discerning accurately the logical structures and relationships of things. Of realizing how everything fits together and correctly putting everything in its proper place. Some people are very good at this. But at the same time, those same people can at times become lost in this understanding and fail to apply the course to move vertically. The "study" of the course then becomes a handicap that keeps them from opening their minds and actually encountering reality.

I think for the most part the ideal is to be proficient at both. We need theory in order to help us to make sense of things, to guide us in the right direction, to clarify meanings, to have a proper framework so that you know what you're supposed to be doing and why. But to also then take that and use it, apply it, live it, look at how it works in your life, use it to change your mind, to develop trust, to actually open up to reality, to a different kind of vision, and to shift your sense of identity away from the body. As the workbook begins:

"A theoretical foundation such as the Text is necessary as a background to make these exercises meaningful. Yet it is the exercises which will make the goal possible. An untrained mind can accomplish nothing. It is the purpose of these exercises to train the mind to think along the lines which the course sets forth."

So yes you need to be pretty accurate with the theory, but the purpose of that is so that you can be more effective and efficient in your application of it to your life. Your living curriculum of lessons, holy relationships and life events is where you will be having to apply the principles.

"The miracle is the means, the Atonement the principle, and the healing is the result."

It's not enough to be excellent at the theory and not apply it to change yourself. It's not enough to try to change yourself while being absolutely all over the place on the theory. If you really want to shoot for the stars you need to understand the course in principle, and apply it in practice. The two work together to atone your mind correctly, heading in the appropriate direction for the appropriate reasons. Otherwise it's like sailing your boat in the wrong direction.

As Jesus once said to me, "you understand it, now you just need to apply it."
