On Lessons 1-4, radical uncertainty and The Dragon. 
A recent dialogue from our  studygroup: 
STUDENT A: To be sure, Lessons 1,  2,3 question the notion of "direct experience," and show that one is supplying  all meaning to direct, empirical experience.
1. Nothing I see in this room  ....... means anything.
2. I have given everything I  see...... all the meaning that it has for me.
3. I do not understand anything I  see.
4. These thoughts do not mean  anything.
It should be also clear we are also  giving meaning to all direct experiences of what is alleged to be direct  experiences of such things termed as "ego,"  Christ, "God," "Sonship,"  "Oneness."
This is self evident in the sense,  the "direct experience," allegedly beyond concepts and beyond judgment, are put  into to word and concepts or given meaning. Given meaning certainly implies both  judgment and concepts.
In addition, while "direct  experience," can give confidence as a steadfast source of truth, its also  obvious that the direct experience of say a Christian Heaven, with angels and  streets of gold by a Christian, is clearly not evidence to everyone, not even  all Christians, that Heaven is paved in streets of gold.
In the same way, large doses of  morphine reportedly often produces an ego-less state of non-boundaries. Whether  this ego less state is later described as a side effect of morphine or as an  experience of Oneness is clearly a process of giving meaning and significance to  the direct experience, which in turn clearly gives meaning to any "truth,"  extracted from the experience and expressed in words and concepts.
However in ACIM all expressed  thoughts extracted from alleged "direct experience," are subject to lesson 4:  these thoughts do not mean anything.
Which to many obviously applies the  direct experience of  a Christian heaven by a Christian expressing the thought  of a Christian Heaven, but not acceptable to many who claim a direct experience  of God or Oneness and wish to similarly express a thought or concept about this  experience. In this sense, the students' expressed thoughts about Oneness are as  meaningless as a Christian Heaven.
To be sure, what is being described  here is a system of self-referencing thoughts/language creating a intractable  condition of radical uncertainty --in other words, there is no condition  including direct experience which cannot be subjected to deconstruction, radical  analysis and reductionism to be rendered meaningless. In other words, what is  described is a thought system of fear whose purpose is to render reality  meaningless, and demonstrate itself real by both making the real, unreal and  suspect, while not subjecting itself to its own deconstruction.
Again and to be sure what is being  describe is intractable in the sense, that all obvious and common spiritual and  religious tactics and strategies for transcending and establishing what is real,  or "center and origin," are self-referencing and only entrench the thought  system of radical uncertainty. To me the point of lesson four is to demonstrate  a self referencing loop of ultimate meaninglessness.
If one reads the author closely  there is a way out which is not itself rendered meaningless by lesson 4. But  this way out of a self-referencing thought system has little to do with the  common tactics and strategies of spirituality and religion which for the most  part are conducted as teaching discourse, or exploiting various self-referencing  paradoxes of the thought system, as an alleged tactic for transcending the  thought system whose purpose in radical uncertainty, into question. A tactic  which clearly only reinforces radical uncertainty and perpetuates the thought  system of fear/lack/uncertainty.
STUDENT B: As I understand the ACIM  wb, the first half is to clear the mind of thoughts that get in the way of  healing and the second half is to fill it with thoughts that help with  healing.
STUDENT A:  Fair enough. Now if you  wished to hold a thought, such as "God is love," how would you know this is a  meaningful thought which could helpful healing the mind, and not a meaningless  thought by apply lesson 4?
 Isn't it obvious that truth is  being associated with meaning? Furthermore a meaning which is not arbitrary and  does not change? Moreover, isn't it clear that we cannot establish a meaning  which is not arbitrary and cannot change? How exactly could you do  that?
 As such "God is love," is a  meaningless thought unless its meaning is first established outside a  thought/language system incapable of establishing anything but arbitrary,  constantly changing meaning.
 What this indicates is "meaning,"  is contextual. Something which is established as unchanging operates as a  reference point, origin and source. Conversely, without source or origin  all is  discourse-- or self referencing words generating a linguistic reality where  meaning is constantly morphing and changing.
It is obvious that people give all  meaning to so called religious/spiritual experiences in the same way they give  meaning to what they see, and what they think. Given meaning is "meaning" which  is arbitrary and changes. As such, lesson 4 applies.
STUDENT C:That's what is meant by  it can't actually be shared, John. Every individual has at least a slightly  different perspective of shared experience
STUDENT A: The reason one has  different perspectives is different people are supplying different  meanings to  experience. Clearly to the extent people supply arbitrary meaning then any  shared agreement is but an agreement about shared meaningless under the illusion  the sharing establishes meaning. Again lesson 4 applies.
STUDENT C: We can't do that with  personal experience. We can only communicate it verbally and either accept or  reject it.
STUDENT A: Again, one gives all  meaning to private,  personal, mystical or spiritual experiences.
STUDENT D: The types of  "experiences" I know of that the Course esteems:
 1. Revelatory experiences;
2. Miraculous experiences;
3. Visionary experiences;
4. Holy Encounters;
5. Holy Instants, and;
6. Prayer.
2. Miraculous experiences;
3. Visionary experiences;
4. Holy Encounters;
5. Holy Instants, and;
6. Prayer.
STUDENT A: What I think is these  above experiences are highly personal, and clearly mean nothing if there is no  personal self -ie, soul/individual spirit,  As such they can only be a  demonstration of the soul.
Furthermore, like miracles, such  experience are not to be used to inlicit belief in one's personal power and  spiritual authority.
 Let's step back and talk in  broad terms. Wouldn't you agree that one  of the most important characteristics of course study is competing, often  mutually exclusive interpretations of the source  material?
Second point: Isn't interpretation of the  source material a process of giving meaning to ideas offered by the  author?
Question then ---does the course material  itself offer the solution and resolution for conflicting and mutually exclusive  interpretation?
STUNDENT B : I would say that it does but  I would say that the process it offers is a process of getting rid of ego  obstacles to understanding the meaning its Author
STUDENT A:  Okay. Now is an interpretation  of solipsism a clear demonstration of a meaningless world made meaningfully by  supplying the meaning of "Oneness."?
Or conversely, is the interpretation of  "other," ie, Father, Son, creation, individuality, etc, meaningful only because  the ego is supply the meaning of these terms?
How is this resolved?
One resolute move is to subject all  interpretations to lesson 4. In other words, all interpretations are  meaningless.
Now don't panic. And don't prematurely  attempt to  force meaning on the meaningless by various means.
Ask yourself if we have found one  certainty --that all interpretation of ACIM are meaningless?
Remember we can always argue that even  this certainty is meaningless but only at the expense of perpetuating over all  uncertainty.
Now ground yourself. Isn't this your  intuition that all course interpretation, including your own are at best lacking  or incomplete?
STUDENT C: I would say the Holy Spirit  gives the correct interpretation to each student depending on where they are at  that moment.
STUDENT A: I'd say that assumes a lot. The  Holy Spirit is not necessarily involved with everyone who describes himself as a  course student. Moreover and clearly, the Holy Spirit is not necessarily  involved even with those who claim guidance from the Holy Spirit.
Moreover the notion of an  "interpretation," means giving meaning to words/ideas given meaning by the  author which by virtue of interpretation must assume the author's meaning is the  object of study and hence the only meaning important.
This contrasts with the notion of text as  a tabla rasa --or "blank slate," where interpretation means projection of  meaning on words and ideas, where the reader is in competition with the author  for the meaning of the text.
In either case, the mind is uncertain and is estranged from the meaning given by the author.
In either case, the mind is uncertain and is estranged from the meaning given by the author.
That said --clearly the correct way to  study and apply ACIM is by direct guidance from the Holy Spirit. This solves the  practical problem of clarity if not complete certainty of interpretation for  some students but not all.
However this does not solve the practical  problem of competing and often mutual exclusive interpretations all supported by  claims of guidance from the Holy Spirit, which confuse students before they  establish direct guidance from the Holy Spirit, if they ever do.
STUDENT B: Ok, you are asking how we might  resolve two very contradictory understandings of ACIM and asserting that one  method we might try is to take these interpretation and remind ourselves of an  early workbook lesson designed to undo our existing way of thinking at the time  when we first do the workbook, namely the lesson: These thoughts do not mean  anything. If we use this lesson, you state, the one certainty we might arrive at  is that any and all interpretations of ACIM are meaningless. Further, you note  that we cannot really argue that this single miserable little certainty we now  have is itself meaningless because doing so would perpetuate our general level  of uncertainty. I am not sure how you argue that because our thoughts are ALL  meaningless or they are not ALL meaningless and if the certainty we have arrived  at (no matter how stingy a certainty it may be) is not meaningless, then the  idea that all our thoughts are meaningless must be false.  Moving on, yes, it is my intuition that all course interpretations, including my  own, are incomplete. Nonetheless, it is also my intuition that some  interpretations are way more complete and accurate than others.
STUDENT A:  Not false --but meaningless.  Yes, all thoughts (which are not our true thoughts) are meaningless. False and  meaningless are not the same notion.
Meaningless not in the sense these  thoughts of which one is aware are not given an arbitrary, changing meaning, but  rather meaningless in the sense that the meaning given, is arbitrary and  changing. 
Now back to the concrete. This tracks with  what we observe. Indeed words and ideas offered by the author are give arbitrary  and changing meaning by the reader/student/interpretor. 
You cannot honestly deny you do this in  interpretation, nor deny Wapnick, Renard, Perry, etc also do this.
In other words, we are clearly defining  and giving meaning to thoughts/ideas/concepts such as "God," "Son of God,"  "communication," "Oneness," "love," etc, by our own admittedly limited  understanding. 
The notion here is "interpretation" is a  process of the mind in the condition of uncertainty, ie perception. We cannot  therefore claim that the product of interpretation, in this case interpretation  of text produces a condition of certainty --or the condition of knowledge/One  Mindedness --rather we are forced to admit any interpretation of ACIM is  arbitrary, and changes, thus uncertain, and thus meaningless. 
The value here of applying the first few  workbook lessons is it punctures inflated ego certainty over interpretation.  It  would seem to me Renard would have been better off, if he had applied lesson  1  when he first saw Arten and Pursha as objects in his living room.  In other  words, nothing in this room means anything. 
Similarly, it would seem wiser if Wapnick  had applied the first few lessons when he reasoned that the author could not be  Jesus but unconditional love given the form of Jesus by Helen's mind. After all  this move is a blatant supplying of meaning to text. 
Again and similarly, rendering meaningless  by lesson 4 punctures inflated ego certainty of students like Carrie who wish to  present with all certainty that "no one else is there," and "I don't exist,"  which clearly pushes any envelope of meaning and which she can't begin to  explain without it being obvious that she is at every point supplying  her own  meaning to interpretations of interpretations.
So yes, I'm willing to say in all the  above cases, by lesson 4, these thoughts do not mean anything. Consequently,  these interpretations are meaningless and all conclusions drawn from these  interpretations are meaningless, even at the expense of rendering ALL  interpretation of ACIM meaningless for the same reason.
The value in this move is that again, it  deflates ego certainty, high lights and emphasizes the intractable uncertainty  of the mind in the grip of perception, and calls into question the prevailing  assumption of typical religion and spirituality that this intractable  uncertainty can be remedied by "correct interpretation,"or a correction from the  up -down, rather than from the bottom (or foundation) up.
To be sure this move must generate an  awareness of the condition of radical uncertainty.
Which is a good thing. Its honest.  Moreover, by its acceptance leaves open the door to question at a deeper level,  if one desires certainty as  a value, in other words, truth as a value, how can  one attain certainty from a condition of radical uncertainty?  In other words,  if in fact there is a condition of unchanging meaning --ie, unchanging, absolute  truth --how do we discern the meaningful from the meaningless?
STUDENT B:  But you are holding that the  statement "my thoughts are meaningless,’ (LESSON 4) is not meaningless but a  useful understanding that can be applied to help people better grasp that there  is a certain inherent uncertainty about their interpretations of ACIM. (And God  knows something like that appears to be needed!)
STUDENT A:  Yes, exactly. Not only a  "certain inherent uncertainty," but rather a radical, largely intractable  uncertainty.
STUDENT B: So if the statement is not  meaningless, then it is a meaningful claim which is to say that it is of a  thought system where truth and falsity can be determined and have  meaning.
STUDENT A:  Exactly. The statement is a  meta comment about thinking. In other words, a comment not from within the  thought system of ego/perception, but rather from a thought system (One  Mindedness) outside the ego/perception thought system, where truth and falsity  can be determined because the thought system was established by God through  laws.
 As such the comment is about authority to  establish reality/truth/meaning, and the mind's conflict over true authority at  the expense of not attaining authority and autonomy but a meaningless world,  that it would not want if it were in its "right mind." Hence all ideas we hold  within and depending on the context of the ego thought system are meaningless in  relationship to the thought system of One Mindedness. And that is demonstrated  by the ego's thought system to provide anything but temporary, arbitrary and  always changing meaning for its own thoughts.
STUDENT C: Unfortunately, I have seen too  many students take the ball tossed to them via Lesson 4 and try to run with it  all the way down the field, doubting that they can know a damn thing. They put  all their trust in Doubt as if it is God.
 
STUDENT A: Exactly.  Now consider the spirit of deconstruction, extreme  analysis, unrestrained reductionism, and radical doubt as the power of "the  dragon". The dragon's power competes with God over authorship of reality. Hell  the power can even deconstruct God. It can deconstruct reality and reassemble  reality in to any constellation of meaning of its choosing. Unrestrained, the  power of the dragon must lead to a condition of radical doubt and  uncertainty.
 In this sense, in the beginning lessons,  the author is using the power of the dragon against itself. In other words,  rightly deconstructing the deceiver and would be destroyer of God's reality. The  dragon doesn't like someone riding the dragon.
STUDENT C: Aha! I actually (and finally)  understand!
STUDENT A: Now take the statement, "I  don't exist," or "No one else is there."
Are these quintessential dragon  statements?
If you don't know or are indecisive or  unsure. You will be eaten by the dragon.
Its hard to destroy the dragon when you  are in the belly of the beast. And most of us are in the belly of the  beast.
So what is it? Are you God by virtue of no  one else being there, and you are resisting God-hood because your own ego-dragon  resists giving up up the world, bodies, individuality, and  personal  existence?
Or is this a seduction statement of the  dragon seducing you as the "only one there," while promising you the authority  of God to establish reality.
You have exactly 20 seconds to decide  before the dragon eats you or you thwart the dragon.
The seconds are ticking, one, two, three,  four . . ... .
