It seems like a tall order to not believe this world is real. I've been immersed in believing it's real for so long.
A result of believing it's real, and trying to become more spiritual, is that I sometimes judge the world or label it. For example I'll say this world is bullshit. Well, technically it's true. But if I look carefully, I have actually made the world real first while believing that I'm taking a higher ground, and am then "separating myself" off from it by judging or labeling it as wrong.
I have to be careful now to notice whether my responses are to a belief that this world is real, like, "its really insane", versus, recognizing that it is not real. I see that many of my "spiritual" perspectives are actually based in pushing this world away.
I've felt a strong sense of inspiration towards the things of Heaven, wanting to be with God, etc.. .but at times the ego comes into this and uses it to try to create separation between me and the world. The world may not be real, but there is a difference between me understanding it intellectually, and whether I am actually recognizing and perceiving and experiencing it as unreal. And if it is unreal, then I have no real basis for having these "spiritual reactions".
Sometimes for example I've been labeling the world as wrong or insane or bullshit or an illusion or that sickness isn't real or there is no death etc, only to then turn around and "react" to a perception of the world by trying to move into a space of "being more spiritual". This is really a form of denial. If the world really isn't real, then it should not create these compulsions to "escape" from it.
Saying the world isn't real is one thing. Actually getting to the place where I believe it solidly and don't react to its appearances is another.
There is a series of workbook lessons which I feel encapsulate the whole transition from 'world is real' to 'world is not real' and the various stages.
128: "The world I see holds nothing that I want."
129: "Beyond this world there is a world I want."
130: "It is impossible to see two worlds."
131: "No one can fail who seeks to reach the truth."
In 128, Jesus highlights how we are not seeing 'this world' correctly, and instead are projecting 'hell' onto it. That means we are making separation real.
In 129, Jesus talks about another world - a perceptual world of true perception, in which this world is seen "as is", revealing the "real world" aka forgiven world. Coming to see this world as harmless and forgiven is the challenge I talked about above.
In 130, Jesus talks of how you can't see the world as sinful and innocent at the same time, or as real and not real at the same time, highlighting that we need to be careful to discern if we're making it real still.
In 131, Jesus talks about Heaven, a world beyond this world, which we can reach if we seek to do so, and cannot fail to do so. But coming to see 'this world' as innocent is required first as a stepping stone, a gentle dream of awakening, which prepares the way.
I do see at least that if I can discern that there is a world I'm making real that I react to, and that if I don't do that, then I will gradually learn that this world is NOT real, and the truth will emerge in my awareness that only heaven is real. And that seems to me to be a straight path which leads right to God.
It also means I have to stop believing the world is an enemy. It is nothing because there is no world.
