You will continue to protect, defend, empower, give energy to, support, believe in, have faith in, trust, consider worthwhile, see innocence in, be willing to sacrifice for, side with, cooperate with, and generally try to become one with THE EGO .... so long as you think that it is YOU.
Who wouldn't? Who wouldn't have all of these upholding, sustaining, supporting attitudes about SELF, regardless of what your definition of that self is. If you believe that you are made of what the ego is made of, or that you believe what it believes, you won't care. You will STILL defend and protect and try to sustain it. Even if it kills you.
This is how people choose to die. They are identified with the ego and what it is is made of, what it perceives and believes, thinking it is their SELF, and therefore they are perfectly prepared to do ANYTHING NECESSARY to defend what they think they ARE.
It's a totally "natural" seeming defense mechanism, in the name of trying to preserve your existence, to sustain your "life". Even if it means that by your identity being "the ego", your effort to "defend your life" is actually defending death, and therefore is a choice to die. In trying to save your own life, as the ego, you will choose death.
It's not really that you need to change the ego at all. It's just a sort of machine that is on autopilot doing only one thing, running one story, seeing things one way. It's not ever meant to do things another way. It can't. It's made of the idea of separation. It's made from beliefs in sin and guilt and fear and death. That's all it can ever believe in or be made of. But that has nothing to really do with YOU.
It only becomes something that is to do with YOU - your sense of SELF - when YOU decide to take ahold of it and convert your identity to it. When you believe that what is true of IT, is true of YOU.
So if you believe that for some reason you are sinful, let's say, and are therefore guilty, and therefore afraid of punishment and death, that means you believe that you are MADE OF sin/guilt/fear/death, that these things are TRUE of you, and that's because you've sort of borrowed these things from the ego. You've tuned into the ego and made it YOU. You've possessed it as an identity, to try to change your identity away from your real self, and away from God.
So now that you believe that YOU are sin, YOU are guilt, etc, your belief now is that your *SELF* is these things. And yet, your primary mode of functioning, your "defense of what you are", your "sustaining of SELF" which is completely inherently permanent in the functioning of the mind regardless of your definition of self, will just simply defend that sin and guilt and fear up and down until you're blue in the face. Of COURSE you will defend it because you think it is TRUE of you, and therefore it is your TRUE SELF.
Everyone is defending, protecting, supporting, and trying to sustain, who they believe they ARE. So if you believe you "are" sin, because of something you seemed to do that you thought was really bad, regardless of how much that sucks and feels awful, you will STILL defend that sin up and down like it's the God given truth of you, because if you are IT, it is YOU, and you are just trying to be "true to yourself". It's just that your IDEA of yourself, your view of yourself, is very mistaken and misplaced.
So this is how you latch on to the ego. And because of this, you will defend the ego's viewpoint, you will side with it, you will support it and feed it and give yourself to it, and all in the name of "preservation of my self", you will literally come to believe that death is real for you. That it defines you, describes you, proves you, and dictates you. So you will choose death. This is why everyone who dies has sided with the ego and has CHOSEN death. All death is suicide in the name of "sustaining me".
All people are trying to do is to stay alive - to continue their self - but because they are mistaken about who and WHAT they are, they keep protecting a self that is NOT who they really are, and that self believes in death. So hey presto, death is defended like it's who you are. And what you defend you will get closer to and become one with.
So you don't really actually need to work on changing the ego. The ego is NOT THE PROBLEM. You don't need to defend yourself against the ego. You don't need to, sort of, "undo" the ego as such, because the ego is already an illusion. It' just that you think it is a "real ego" because you have given YOUR reality to it - your sense of real self. The MISTPLACEMENT of yourself is what needs to be corrected.
So like, there's a burning pit of fire with you standing in it the middle of it. Hell. And you have two options how to deal with this. Either a) stay there and try to change hell to put the fire out, or b) get OUT of hell. And those who believe they are their ego will choose a ... they will try to CHANGE hell and to turn it into heaven, by trying to manipulate what the ego IS.
But the ego is ALWAYS, and will always be, a device for death. It does not change. CHANGE is death. The ego cannot change into non-change, and it cannot change into not-death. It is always death. It is always going to be perceiving wrongly, upside-down and inside out. It is always going to see God as evil and it's always going to try to get as separate from God as possible. It is a faithful machine, and that's how you designed it when you MADE it. It's like a car-ride that you invented in you back yard which is hardwired to drive around a fixed track, and that's all it can do. It can't go free-riding across the countryside. It is on rails. It just does what it was designed to do.
Changing the ego does nothing at all. That's a "spiritual ego". That's trying to emphasize the persona and reject the shadow in an attempt to make some PART of the ego be special and good and happy, while the other part is relegated to all the bad stuff. That's not going to work because both parts are still the ego and regardless of whether you try to emphasize the "good or bad" parts of that illusion, it still energizes that illusion and leads to death.
But it's what we've all been doing, trying to be in denial of the fact that the ego is 100% "bad", not 50%. It CANNOT hold the truth. It CANNOT have anything about it that is spiritual. It CANNOT even really exist. Yet here we are trying to dress it up and be selective about it, as if we can somehow redeem it or make it more tolerable or have some kind of option or exception to how it function. The ego is a one-way train to death and THAT IS ALL IT CAN BE.
So your REAL choice, your sensible choice, is to stop believing that YOU are the ego. That is really the ONLY way to wake up from it and be free of it. There is no other way to get off the ride. The ride is going to hell, and you with it, unless you change your sense of SELF. Who you are. What you are. What you are made of.
If you are made of real sin, you are believing you are the ego, and you will die. If you are really guilty, you will be afraid of inevitable punishment. You have no say in changing that dynamic. What you CAN do is recognize that the ego is an illusion, that it is NOT the truth about YOU, and in some way "separate" your sense of identity from it.
You need to get your mind peeled away from the ego, and then hook it back up to God. i.e., to DETACH from the ego thought system, and ATTACH yourself to God's mind/Holy Spirit. Trying to fight with the ego is 100% pointless. It doesn't actually WORK. The only thing that works is letting it go. Not BEING it. Not believing that you ARE it.
That means you must BELIEVE that you are NOT really sinful, you are NOT guilty, you are INNOCENT. God's truth is the truth about you, not the ego's. God's "version" of you is the truth about you, not the ego's version. Your IDENTITY needs to step back and NOT BELIEVE that you are "made of" anything whatsoever that is of the ego. You are not sinful, guilty, weak, afraid, sick, vulnerable, suffering, or dying. Those things cannot be part of your SELF TRUTH. The truth about your SELF. What and who you are.
Your transition away from the ego identity to your REAL identity is what wakes you up. It's your relinquishment of a false idea of who you ARE. A false sense. That's all the ego is, a self that you are NOT. A framework of identity pretending to be an individual, that is NOT who you are, but who you have tried to become through your belief that it is TRUE of you. The ego is not true of you and nothing it believes is true of you. So for you to detach, YOU must be convinced that it is not true of you.
If you are not really sinful, you MUST still be innocent. And if you are not sinful, nothing can have happened. And that means the Atonement principle. Recognizing that IN TRUTH, you are innocent, and therefore CANNOT BE THE EGO. Seeing your real innocent self clearly. That's all you need to get to. The ego will just vanish when you have no further belief in it. It must, because it only seems to exist in your mind because of your belief that you are not yourself.
