Thoughts/attitudes/beliefs/truth on the Holy Spirits level is completely incompatible with the ego's level. Never the two shall meet. So the ego is really confined inside its bubble of private insanity.
Within the ego's bubble, it starts to believe it can ACCESS and thus experience, what it is like in the Holy Spirit's world. It actually wants to do this because it wants to become more powerful, to have more domination and control, and to wield what would seem to be the kind of 'special' powers that Holy Spirit apparently has access to.
Except the ego has a problem. It cannot leave its mindset. It can't *actually* get into the Holy Spirit's mind. So it pretends that it can. And as always, it uses separation to do this (the same old story, separate in the name of joining).
The ego takes its own mindset and separates it even further, dividing it into 'good' and 'bad' parts. All still within the ego thought system. So now it labels some parts of itself/the world as good and some parts as bad. It sort of creates the illusion that it can 'borrow' some goodness from the bad stuff and attribute it to the good stuff, to make the good stuff seem extra special and sparkly and important and valuable. And of course that means taking some of the 'bad' that you'd find in this stuff and attributing it to the 'bad stuff' so that it seems extra bad - a repository for nasty dark judgements and hate and so on.
This creates the persona - the spiritualizing portion of the ego mind which tries to focus only on the 'good' interpretion of the world, and simultaneously creates the 'shadow', which is whats left of all the stuff that is 'not good'. For something to seem good, something else HAS to seem bad. To have special love there has to be special hate. To idol worship there has to be 'the enemy' who clearly do not get what's so special about the idol. And to have all the 'spiritual behavior' you must relegate 'unspiritual behavior' to the shadow. You try to hide everything bad IN the shadow, AS the shadow, and you then try to get RID OF the shadow. Tuck it away, hide it, destroy it. And then guess what happens?
The shadow part of the ego mind, the bad stuff, now takes the symbolic form of all of the enemies, attackers, victimizers, causes of sickness and so on. The 'goodies two shoes' part is the facade of special love and special appearances which 'saves face' and makes it seem like you are MORE spiritual ie more SPECIAL than you are. ie, if you sweep all of the sins under the carpet it LOOKS LIKE you're more innocent than you are. The ego's use of the persona is what gives extra weight to the idea that your persona is valuable, important, special, wanted, loveable (in an ego way), desirable, innocent (ego innocence) etc. And so the 'good ego mind' and the 'bad ego mind' are now AT WAR. Reinforcing the good reinforces the bad because it's like a seesaw - you take less load off the good end to make it seem 'lighter', the bad end gets badder and 'heavier/darker'.
So this ego attempt to divide itself and be at war with itself, which creates the persona and the shadow in conflict with each other (e.g. person who everyone always thought was 'good' gets unfairly attacked or sick etc), allows the ego to lend special meaning to some parts of its mindset - a glow of specialness - sacredness - holiness - spirituality. Not genuine holiness or genuine spirituality, but a fake APPEARANCE of it. A facade. This can take the form of huge sacrifices or changes in behavior, level confusion, trying to be good, trying to not be bad, trying to ATTAIN very lofty levels of 'spiritual advancement and capabilities' that make it look like you're very advanced and special.
Since the ego cannot leave its own mindset and cannot actually become spiritual, it just fakes it. It pretends it is spiritual. And it fools itself. And this is what YOU do. This is what I do. This is where we TRY to attain experiences and mindsets which are OUTSIDE of what THIS mindset (our current ego mindset) can achieve. Our ego mind tries to 'be spiritual', while KEEPING the ego mindset. This is because the ego wants to live in two minds. It wants to take the ego self TO the Holy Spirit and to KEEP it and to at the same time TAKE ON the Holy Spirit's power. Obviously this cannot be achieved because the Holy Spirit's mind completely dispels the duality that the ego is based on, and completely undoes it. But that doesn't stop our ego from trying!
So whenever you are KEEPING the ego mindset and are trying to INCLUDE spiritual mindsets in some way, you are spiritualizing.
Whenever you try to express, quote, espouse, affirm or act is if you are being or accessing spiritual truths which are WAY higher than the ego's mindset, and you cannot actually ACCESS and experience the level of mind where those truths can be EXPERIENCED, then you are spiritualizing.
So let's see... course quotes and concepts... for example the idea of oneness. You could say to someone like, "it doesnt matter because we are all one". Bullshit. This isn't an EXPERIENCE of the truth of that statement. You can only experience that at a level ABOVE the holy spirit in the mind of HEAVEN. That's the only place where this truth is experiential. Remember, truth is what you can experience. If you cannot experience it, you're kidding yourself every time you make statements about it AS IF you are living it.
Or how about even saying, "I am immortal spirit"... well.. not as an ego you're not. Who is saying you are immortal spirit? It's the ego. You can only BE immortal spirit when you have completely let go of the entire ego mindset. So this information is just... information from another world, from another dimension, another state of mind. Thus it has no PRACTICAL USE for you here, on the ego level, because you cannot EXPERIENCE it here. So it remains lofty. It remains a concept. And then if you spend time just regurgitating the concept, stating it, quoting it, because it 'sounds spiritual', then you are spiritualizing.
You're taking very high truths from very high levels of mind, which require AT LEAST a total atunement to Holy Spirit's mindset AND a total relinquishment of the ego's way of experiencing, and are trying to bring them INTO the ego's mindset. This is spiritualizing. Adding spiritual value to a valueless system. Borrowing spiritual truth from a level of mind that is beyond where you are at. That's faking it. That's spiritualizing your ego. And what happens then is that the best you can do is quote these things and say them and affirm them as if doing so is EXPERIENCING them when in fact you cannot experience them yet, and so they remain MENTAL, and that makes them INTELLECTUAL. Thus you end up intellectualizing the course's truths, you intellectualize higher levels of reality and you pretend that doing so means you are experiencing them here and now. You're not. The ego is deceiving you and trying to be special. And this makes these truths BECOME nothing more than specialness. And then you end up sounding like a bliss ninny, lol
Anyway. I'm sort of expressing this as it's coming to me.
You need to be realistic about the level that you're on, what mind you are IN, the scope of that mind, what is OUTSIDE that mind, what you can actually EXPERIENCE right now, and stop hitting yourself over the head with these lofty spiritualizing ego-inflating truths which you can't even experience yet. You need to focus only on the truths which you can PRACTICALLY APPLY, ie BE EXPERIENCED, to help you to transition your EXPERIENCE from what you are experiencing now in the ego mind to what Holy Spirit will allow you to experience in his mind. If it does not involve your experience, and if it is not practical and you can't actually USE it to change your experience, it is intellectual ego noise trying to spiritualize itself.
I know that I have done this over any over again, believing that if I could just say the correct thing or think the correct thought or understand the correct concept or say it in a special way, that meant that I am BEING IT. I believed that my intellect had the capability of experiencing the truth. Hah. It doesn't. The intellect is only activated when you are not able to LIVE the truth, but are trying to incorporate it into your experience, so you can inject it into your THOUGHTS, which are fantasies, and you can pretend you are living it, but really you are not. If it's stuck in your mind and isn't in your heart or in your feeling or in your actual direct experience of 'reality', then it's not really your truth right now. And if you accumulate a lot of that 'information', no matter how spiritual it is or how lofty the metaphysics, if you are not EXPERIENCING it, then you are spiritualizing your ego. This is what I have done over and over again.
All you are capable of is letting go of the ego mind and the way of experiencing that that mind gives you, and transitioning your experience of reality to the holy spirit's mind where you can experience HIS level of truth fully. Where you can LIVE IT. A course in miracles is all about LIVING the truth and PRACTICING it and PRACTICALLY EXPERIENCING it. The rest is just ego noise.
