False perception means you are looking at something in such a way that you do not recognize what it is.
If the thing you're looking at is false, your mind will think it's true.
If the thing you're looking at is true, your mind will think it's false.
Although it's called false perception, this can be misleading because it makes it sound like it only focuses on falseness. But being a "false" perception, it's really a state of mind that INVERTS EVERYTHING.
What is true is swapped with what is false. What is false is swapped with what is true. That's all part of "perceiving falsely." Perhaps it would be better to call it inaccurate perception or mistaken perception.
If the world itself were a reality, an inaccurate perception would make it seem unreal. An inaccurate perception would distort whatever the world is, and show it to you as it is not.
If the world itself were NOT reality, an inaccurate perception would make it seem real. An inaccurate perception would distort whatever the world is, and show it to you as it is not.
So being in false mistaken perception doesn't inherently tell you whether the world itself is real or not. It only tells you whether you are in a state of mis-perceiving or not. Whether your mind is distorting or not, inaccurate or not, or deceived or not.
However, Jesus does refer to false perception in contrast to true perception. Perception is "true", or correct and accurate, when it is lining up more closely with facts and isn't introducing mistakes. A truer perception becomes somewhat transparent and stops interfering with what's being perceived. It kind of gets out of the way and reveals something "as it is", rather than interpreted incorrectly.
Nevertheless, even a true perception does not tell you whether the thing you're looking at is true or false, real or unreal. In and of itself perception does not determine this. All a true perception does is it stops distorting vision and takes a direct undistorting look. Whatever is there, no matter whether it is real or unreal, will be seen more for "what it actually is."
But what something "actually is" does NOT inherently tells us whether the thing actually is true, or actually is false, in its own right. Seeing a world truly does not mean that you automatically are looking at a true world. You can see a false world truly as well. You can see a word of fiction truly, just as you can see a work of non-fiction truly. You can see a fake world just as accurately as you can see a real world.
So at no time does perception actually tell us in any way, WHETHER or not the world is INHERENTLY real. It does not tell us if the world is genuine. It doesn't tell us if it is God's creation. And it doesn't tell us whether the thing perceived is really there.
Part of this comes from the fact that "projection makes perception". This means that you in fact have to PROJECT something out first, in order to perceive it. And you can only perceive WHAT you project. And you perceive it because you believe in it, and WANT it to be there. You look within at what is inside of you, and you project it out, and perceive its projection, which REFLECTS back to you like a feedback loop and you perceive it. This is why Jesus says:
"Perception is a RESULT, not a cause."
Perception does not cause anything, it does not define whether what you perceive is real, it does not give us any facts, and it does not prove whether the world is real or unreal. All it shows us is WHAT WE ARE GIVING, and what we therefore are CHOOSING TO SEE. And we see whatever we WANT or wish to see, projected out, because WE PUT IT THERE to see.
The question then becomes, do you actually ever perceive "an objective world", in its own right, in its own nature, or do you ONLY perceive what you project ONTO it? And how is it that you can project something onto it in the first place?
If the world were, let's say, completely real and God created, it should not be possible to project ANYTHING onto it at all. It should not be possible to modify it, define it, shape it, interpret it, or in any way have anything to do with "what is there." God by his will has put a world there and it would then be our job to accept it as it is and know it and be one with it. It would not be possible to "project perception".
That it IS possible to project perception onto "this world", the world we recognize as Earth etc, tells you that this world cannot have any INHERENT MEANING of its own. It has to be able to reflect what you project, and it can only reflect it because it is neutral. It is neutral only because it is nothing, and being nothing it has no inherent truth of its own. How could you project false things onto it, OR true things onto it, if it had ITS OWN truth? Its own truth would fight with and block anything you tried to give it.
Perception therefore really hints at us to realize that "there is no world apart from what you wish." There is no world apart from what you give to the world. There is no objective world out there. What we're projecting onto is an emptiness and an illusion, not a reality. What we're perceiving things IN is a mirror. We only see what we put there, otherwise there would be nothing TO see.
Note that perception is feedback, and it is a feedback from what was projected out.. True perception is less distorting that false perception, and could potentially become more transparent, to where it could "see past" what is projected to the underlying inherent nature of the world. To see it for what is actually there. But if there isn't something real actually there, true perception should also reveal that the world is unreal.
We need to realize that true perception does not mean that you see "the truth" as if it is the objective truth. It means that you are seeing in a "true way", such that WHATEVER you see won't be distorted. You are projecting an idea of love which makes the least amount of distortion or misinterpretation.
Seeing truly is only accurate vision, which DOES NOT IN ANY WAY indicate whether WHAT you look upon with it is, in and of itself, actually true or false. True perception can just as easily look upon a FALSE WORLD, and recognize "the truth that" it is a false world. True perception is not "blindness" to what is false, and we must not confuse WHAT is seen with HOW it is seen. You can look truthfully upon and lie and recognize it is a lie, just as much as you can look truthfully upon something that is inherently true in and of itself. True perception DOES NOT tell us whether the world is really there or not!
You can see that perception really has absolutely nothing to do with establishing whether or not this world exists, whether God created it, whether what you see is true and real, or what the inherent nature of the world is. Even if you see love in it, even if you see reality in it, even if you see God reflected in it, it STILL does not prove that the world is objectively real. Beyond what you GIVE to the world, or what you MAKE OF it, you have literally NO IDEA whether the world is really there or not.
True perception can potentially show you "what is there", but it doesn't of itself tell you what "it is." True perception is just as capable of showing you that THE WORLD IS FALSE.
"Projection makes perception; the world you see is what you GAVE it, nothing more than that."
"The world can give you ONLY what you gave it, for being nothing but your own projection, it HAS no meaning apart from what you found in it, and placed your faith in."
"The power of decision is your one remaining freedom as a prisoner of this world. YOU CAN DECIDE TO SEE IT RIGHT. What you MADE of it is NOT its reality, for its reality is only what you GAVE it."
