I think I made a major mistake when starting out with the course. It was fuelled by a rather "negative" view of the world, which was part mine, and part that of certain teachers I listened to. In that view, I thought that references to a meaningless world, were references to a the world being inherently bleak and dark and depressing. I also combined various aspects of ego and false perception with the world, binding them together, and then sought to get rid of the whole thing.
This was based largely on teachings by well-meaning people that the world has no redeeming qualities, that it is inherently somewhat negative and pointless, and that the only thing to do is leave it behind. While there is some basis for this, in that the world is nothing, it kind of skipped over the forgiven world/real world and didn't put enough attention on how to reinterpret or repurpose it. And it definitely didn't make much mention of doing anything to improve or heal or save it.
This was an incorrect framing of the world, because I realize now that the world itself has NO meaning, not a negative meaning. Its meaningless is simply a lack of ANY meaning, positive OR negative, and is not inherently anything. And my egoic association of the world with my ego's negativity didn't allow me to "separate out" the world from my projections onto it.
But the course isn't asking us to condemn the world and run away from it. It's asking us to realize the world is nothing at all, but that we've projected false meanings onto it. And when these false meanings are lifted off from it, the world resumes being meaningless. Not negative, or positive. And then we are free to project positive meaning onto it, in which we now see the reflection of God.
This obviously makes far more sense, interpreting the world as a neutral mirror with no meaning of its own. It also changes my focus, from one where I just wanted to escape from "the negative world" and throw it in the trash, to where I can now look at the very same world - its guts, recognizing it as nothing, but project love onto it. That's a profoundly different relationship to it, properly regarding it as nothing but a mirror with no meaning of its own, rather than as bound to ideas of hell.
It changes quite a lot of my perspectives about the course and what it's saying. It also relieves pressure and resistance and negative connotations to things which didn't seem to fit. I can accept then that I can see this world through forgiving eyes because of itself it is nothing. And it also makes it easier to accept that it can be used differently, and can reflect heaven. Obviously keeping it around long enough to allow it to do that can't entail attacking it with misinterpretations of the course.
Eventually when seen as the nothingness it is, with the reflection of God seen upon it, its re-purposing is complete and it is no longer needed as a device to bring us home. We can now wave farewell to the forgiven world and thank it for its temporary usefulness, as we watch it disappear and give way to the gates of heaven.
The key part I think is that a lot of people have completely missed the somewhat subtle teaching in the course that the world ITSELF has no meaning. That it was a projection out, from an idea of nothingness, BEFORE we projected onto it. The whole "projection makes perception" thing came later.
And the world doesn't have to be objectively real or a creation of God for it to act like a neutral mirror and still be a world of illusions. This two-layered projection is completely missed by a lot of people. And some interpret the world as having to be God's creation in order for the "project onto" part to make sense. Which is yet another mistake. So many of us are so confused about this whole thing. But I'm glad now it's becoming ever clearer.
