Jesus says: "I am the teacher of the ego."
He also says "The ego is the idea of selfishness."
Now, consider this. Your mind is either in a state of sanity or a state of mental illness. When mentally ill, YOUR MIND is "being selfish". It believes in specialness. But when that SAME mind chooses not to be selfish, that mind returns to sanity. The selfishness itself is gone, and the mind remains.
So if the ego is the idea of selfishness, the ego is also the idea of or a label for "the illness" that seems to be occurring when YOU are mentally ill. It is perhaps far more accurate, then, to consider "the ego" to be more of an ATTITUDE, than a THING.
We should not think of the ego even as "the ego", because there is great temptation to label it as a "something" that "is not me" and to then seek to identify with Spirit in an effort to "dis-identify" from "the ego". There is some positive benefit to that "positive separation", but this implies the ego is a distinct something that exists separately from you. This results from putting the ego in a box and not realizing it is coming FROM your mind, and part of your mind is being thrown out in that same box.
The ego is not "separate from you", it has to live within your mind because ideas leave not their source. "The ego" is your bad attitude. It is better to think of it as "your egotism" than "an ego". Or similarly as Jesus says, it is YOU BEING SELFISH. And being not-selfish does not erase your self, nor does it require you to "separate from" the mind that was being selfish. The mind itself is not the problem, its attitude is the problem, and there is temptation to throw out the mind right along with the egotism.
Someone or something needs to learn. Someone or something is taking the course, learning the lessons, pursuing a curriculum. Who or what is learning? In a sense, the self - you, your mind, is the one learning. And this mind is learning "not to be egotistical". So its egotism is coming under scrutiny and it's having to learn to adopt a more loving attitude.
When the mind is believing things which are false, it is believing "in the ego", but moreso, is "believing in something false". This doesn't mean there is now an entirely separate ego "entity" that has come into existence. Or even really what we can label as a "false self".
Your self never becomes false, it is permanently in the sight of God, holy forever. What becomes false is your relationship with reality through the mind and YOUR attempt to block it. And that's more a matter of YOUR attitude and YOUR attempt to change reality into something else. It's still entirely within the realm of your will and your power of decision, as to whether and when you take the curriculum and learn your lessons.
It is YOU that is being educated, and while you are mistaken, you are "being an ego". ie you are ATTEMPTING to be ego. In pure purest most logical condition, "the ego" is really another word for "non existence". It's the logical opposite of existence, reality, truth, life and God. But such an idea literally does no exist, it is nothingness. You cannot go there, you cannot be it. So even in our egotism we HAVE NOT become "a non-existent self", or purely real death. It's literally impossible.
Our egotism is merely the ATTEMPT to, and failure to be, separate. It's our desire and belief and wishful thinking to be something we are not, but in such a way that can never succeed. You can't destroy yourself, and the only way to be purely ego would be to not exist. We attempt to get as close to that as possible, in death, but even that doesn't do it. We can't get outside the bubble of God's all encompassing love.
So what is an ego? It's not really anything. There are just some people who are confused. There are just some people whose minds have taught themselves things which aren't true, and whose minds need correction. And so those minds, although being egotistical and selfish, and seeming to therefore exhibit signs of "the ego", are really just minds in a state of denial and being mistaken. And mistaken minds can be corrected and healed.
So that means our egotism can be healed. Our mistakenness can be forgiven. We can be taught. Our "egoic selves", really a mind having an egocentric attitude, can be adjusted so that the egocentricity is "undone", the distortions of the mind untangled, and the mind restored to a state of accord and wholeness. This essentially means in a way that "our egotism can be converted to holiness".
"Ego", more as a label for "being egotistical", can be undone. And "our ego" is kind of "transformed" along the way BACK to the state of a holy mind that it was in previously. It can become untwisted and untangled. Corrected and healed. Not because the illness is changed into reality, not because the egotism ITSELF is maintained and becomes holy, but because the egotism or illness is just a label for the temporary states we APPEAR to get into when we're mistaken.
If I have mental illness, the illness could be called "ego". But when my mind is healed of the illness, it's not that "the illness" is still an illness but in a healed configuration. The illness is gone, the illusion of egoic stuff is gone, and the mind that "had" the illness is restored to sanity. As "the ego evolves" out of sin into innocence, the ego is simultaneously undone and transcended. IT doesn't become holy as such, we let it go. But "the ego" was always OUR mind's attitude, and our mind is what becomes transformed.
We could try to put all of the ego stuff into a box and label it "the ego" and then try to recognize that our self is really our soul and not the ego. This is sort of true. But this can be a form of bypass because the only thing maintaining the ego is the mind. There is some mind MIXED IN with the egotism.
The mind is "having" an ego, just as it has mental illness but is NOT the mental illness. Mind is not the ego but HAS egotism. When "separating" ourselves off from "the ego", we could risk trying to separate ourselves off from the mind that HAS the ego, causing a further split in the mind. And so this can be another form of disassociation, and another way that "the ego" tries to remove the ego.
This is also why we are responsible for all our choices, all our suffering, and all our mistakes. They are not real sins, but it IS us that is mistaken, not "the ego". Our mistakenness IS just another word for "the ego". Our false beliefs may seem to gather together to form "a sense of separate self" but this is of course an illusion. It can seem like you are letting go of "that self", but the mind that was producing "that self" is not let go. It is healed.
The world plays into this in the same way. The world is a symptom of the presence of mental illness in the mind. "The world is false perception". When the mind is healed, it no longer produces the world of separation. While producing the world, the mind thinks the world exists and it seems to be "a thing", with a label.
But the "healing of the world" or "saving the world" really means saving the mind that was producing the world, from its own selfish egocentricity, so that its dream is a happier dream. The world then appears to transform from hell to a reflection of heaven. Or as Jesus says, it is "translated". And the holy spirit is the "great reinterpreter" of it. A mind that is corrected and healed does not make hell and does not make ego errors, and in this view there "is no ego" because the egotism is gone.
So is Jesus teaching the ego? In a sense yes. He is teaching the mind that is trying to be an ego, that it is not really an ego but a holy mind. The ego, the mistakes, are not taught. They are corrected. Because true learning is correction and undoing, just as to atone is to undo. To truly atone or fix the ego problem, the ego must be undone, meaning the egotism must end, meaning the mind is freed from believing it is "an ego." Thus is "the ego" undone and the condition of the mind changed back to ego-free holiness.
Can the ego wake up? No, because it can't maintain what makes it ego at the same time as experiencing awakening. But the mind can wake up FROM the ego, or rather, FROM attempting to be egocentric. As "your egotism" or "the part of mind trying to be separate" learns not to be separate, the mind that was being ego DOES wake up, but it does not take the egotism with it. It wakes up BECAUSE "the ego" is left behind, ie by recognizing there is no ego within it. We do not "separate from" the ego. We erase it from ourselves so that there is nothing to separate from.
Ultimately there is no ego, and the Holy Spirit knows this. His is the mind that reminds us of our true condition of holiness. The recognition that we are sane and whole and true. And in that holiness there is no selfishness, specialness, or egoic attitude. Only an attitude of love and forgiveness. And a loving forgiving mind is ego-free.
"Forgiveness through the Holy Spirit lies simply in looking beyond error from the beginning, and thus KEEPING it unreal for you. Do not let any belief in its realness enter your minds AT ALL, or you will also believe that you must UNDO what you have made, in order to BE forgiven. What has no effect does not exist, and to the Holy Spirit, the effects of error are TOTALLY non-existent. By steadily and consistently cancelling out ALL its effects, EVERYWHERE AND IN ALL RESPECTS, He teaches that the ego does not exist, and PROVES IT."
