We do not recognize an illusion when we see one. Since birth we've been looking at this world believing it's real. It seems real enough. But "there is nothing so blinding as perception of form."
The problem is, we don't have something MORE real to compare it to. There is no frame of reference to evaluate it or contrast it. If you could see something truly real, it would frame this world AS an illusion, it's illusory nature would become obvious, and you would be able to tell that this world is clearly false and unreal. But you have to have a sense of what true and real things are like in order to be able to compare and contrast, that this illusion is opposite to that.
Think for a moment then about reality, about God, about Heaven, about the nature and quality of infinite immortal being. Contemplate what God is like. The eternal nature, the endlessness, the freedom from sickness and death, the inability to create anything less than perfection. Then ask yourself, is this thing you are looking at, THAT? Does it match up? Does it correlate? Does it seem like something God would create, something immortal, unlimited, perfect, beautiful and pure?
"The world you see is an illusion of a world. God did not create it, for what He creates must be eternal as Himself. Yet there is nothing in the world you see that will endure forever. Some things will last in time a little while longer than others. But the time will come when all things visible will have an end."
With something to compare it to, it becomes more obvious that the things of this world, the stuff you've been looking at since birth, MUST BE an illusion. It must be something manufactured, artificial, pretend, fake, unreal, deceptive. It cannot really exist. There is no cancer in God. There is no insanity in God. There is no dog shit in God. There is no crying in God. There is no attack in God. There is no fear or threat or danger in God. Can this appearance of sin and attack exist WITHIN God's perfect being? Not even slightly. So what is it you're looking at?
It has to be something that is not really there. It has to be a lie, an illusion, a deception and a temptation to believe in something unreal. It's some kind of hallucination. It's make believe fairytale dreaming. It can't exist. It can't really be there at all. It seems to be but it's not. It is really nothing, pretending to be something. The impossible, pretending to be possible. It can't exist in God. It has no real cause. It hasn't been created. Remind yourself of this, and it will become clearer and more RECOGNIZED, that what you're seeing is an ILLUSION, some kind of invented puff of smoke masquerading as something else. It can't be real. It can't exist. It's not there. It's gone.
"Illusions recognized must disappear."
There is only God and His Kingdom. "Only the creations of light are real."
