Projection makes perception right?
Guess what? Your mind is so big and vast that it is PROJECTING THIS UNIVERSE.
Guess what is showing up as images IN your mind? Physical objects. Bodies. Mountains. Planets. These are THOUGHTS, IDEAS. All "forms" are forms of error - of erroneous thinking.
These "objects" are the PERCEPTUAL CONTENT of your mind.
This is even WAY BEFORE you even get into whether or not you "look at" this stuff through a body. This is WAY BEFORE you even start asking yourself to "change your mind about the world".
Most people do not realize this. You are not simply asked to change how you LOOK AT a world that seems to be out there "on its own" that someone or something else put there.
You are meant to be learning, that YOU MADE THIS UNIVERSE.
And at some point that DOES MEAN, that because the physical matter of this universe, and all the energy, and everything at the quantum level, is all AN ILLUSION, IN YOUR MIND, IT TOO MUST BE REMOVED.
When Jesus stopped making a body, his body disappeared. "because I had no more illusions about it". He does NOT say, that he changed his mind "about" his body and disappeared off into his mind and left his separate stand-alone someone-else-is-putting-it-there body to rot in the ground. The body was IN HIS MIND, HIS MIND PROJECTED IT.
In similar vein, when our collective MINDS finally recognize that THIS ENTIRE UNIVERSE is an illusion, we will ALL recognize that it is fundamentally an illusion and we WILL WATCH IT DISAPPEAR. LITERALLY.
Precisely as Jesus himself has said:
"And together we will watch the world disappear".
This "world" is not referring to your view OF the world. It is not referring to your interpretation OF the world. It is not referring to what you think about the world. It is referring, plainly and simply, about THIS ENTIRE UNIVERSE, which GOD DID NOT CREATE.
Extraordinarily bizarre false interpretations of the Course's message have arisen out of INCORRECT interpretation of what He means by perception, what he means by the world, and the responsibility that YOU HAVE of having PROJECTED IT YOURSELF. Not just what you project ONTO it. *IT*. You made this world. This is the world YOU MADE with the power of your mind. It does not exist on its own. God did not put it here. YOU DID. And you STILL ARE. And until that ends, you STILL HAVE FALSE PERCEPTION.
