Nothiing in reality can be perceived, only known

This is a potent, and clarifying passage, about the fact that ALL perception (even true) is totally OPPOSITE to reality still. Even Christ vision, even sight of the real world, is STILL a state of separation. "Perception is a separated state." "To perceive the truth is not the same as knowing it." Knowledge is a direct experience of God's Kingdom, whereas perception is a once-removed, separated, interpretative IMAGE-based reflection. Nothing in the world of illusions (including Eath) HAS any truth to it. True perception merely recognizes that the world IS SENSELESS. Teachers of God who choose to look on dreams a while, are NOT DECEIVED by what they see.

"This is a course in miracles. And, as such, the laws of healing must be understood before the purpose of the course can be accomplished. Let us review the principles that we have covered, and arrange them in a way that summarizes all that must occur for healing to be possible. For when it once is possible it MUST occur. ALL sickness comes from separation. When the separation is denied, it goes. For it IS gone as soon as the idea which brought it has been healed and been replaced by sanity. Sickness and sin are seen as consequence and cause, in a relationship kept hidden from awareness, that it may be carefully preserved from reason's light.

Guilt ASKS FOR punishment, and its request is granted. NOT in truth, but in ***the world of shadows and illusions BUILT on sin***. The Son of God perceives what he would see, because perception IS a wish fulfilled. Perception changes, MADE to take the place of changeless knowledge. ***Yet is truth unchanged. It cannot BE perceived, but only known.*** What is perceived takes many forms, but ***NONE has meaning***. ****Brought to truth, its senselessness is quite apparent.**** Kept APART from truth, it SEEMS to have a meaning and be real. ****Perception's laws are OPPOSITE to truth, and what IS true of knowledge is NOT true of ANYTHING that is apart from it.**** Yet has God given Answer to the world of sickness, Which applies to ALL its forms.

God's Answer is eternal, though It operates in time, where It is needed. But, because It IS of God, the laws of time do not affect Its workings. It is in this world, but NOT a part of it. For It is real, and dwells where all reality MUST be. Ideas leave not their source, and their effects but SEEM to be apart from them. Ideas are of the mind. What is projected OUT, and seems to be EXTERNAL to the mind, is NOT outside at all, but an effect of what is in, and has NOT left its source. God's Answer lies where the belief in sin MUST be, for only there can its effects be utterly undone, and without cause.

****Perception's laws must be reversed, because they ARE reversals of the laws of truth****. The laws of truth FOREVER will be true, and cannot BE reversed; yet can be SEEN as upside down. And this must be corrected where the illusion of reversal lies. It is impossible that one illusion be LESS amenable to truth than are the rest. But it IS possible that some are given greater VALUE, and less willingly OFFERED to truth for healing and for help. ****NO illusion has ANY truth in it.**** Yet it appears some are MORE true than others, although this clearly makes no sense at all. All that a hierarchy of illusions can show is PREFERENCE, NOT reality."

This is really key:

"Brought to truth, its senselessness is quite apparent. Kept APART from truth, it SEEMS to have a meaning and be real."

The world is an illusion. Period. Having illusions ABOUT the world, means you are believing the world is real. It means you have illusions ON TOP OF an illusion, and are not RECOGNIZING that it's an illusion.

"the world of shadows and illusions BUILT on sin" "The world of bodies is the world of sin."

Perceiving the world AS REAL, means that it has been kept APART from truth. And therefore true perception is not occurring.

Because the world IS AN ILLUSION, perceiving it AS REAL is a MISTAKE. An error. This is FALSE perception.

Because the world IS AN ILLUSION, perceiving it AS NOT REAL, is CORRECT perception, true perception. When the world is seen with true perception the world does NOT BECOME REAL. It becomes RECOGNIZED AS FALSE. Its senselessness becomes apparent. It ceases to DECEIVE because you do not buy INTO its illusions of temptation.

This world is not real. Nor is is real in the eyes of christ. Believing it is real is a complete 180 degree reversal of what the course is teaching.
