If you get really good at using your persona, you will get really brutal at cutting out things which seem even remotely bad.
Eventually you'll be trying to be SO good and perfect, that there will be practically nothing left to relegate to your 'bad' category. Like you hear people saying, "nothing is ever good enough for them" - a sign of a lack of self acceptance.
And if that carries on, there will be nothing left to get rid of, you will cease to exist. Death.
So you can see, the persona, which seems all sweet and nice and special and important, glowing with a false innocence, is in fact the ego's wish to destroy you, piece by piece, by gradually stripping off more and more parts of you and relegating them to hell, in the pursuit of 'being a God'. And along the way it will complement you on how fantastic your 'good bits' are, even though your 'good bits' are soon to come under scrutiny.
The persona attacks everything that is contrary to what it wants to keep. And its eventual mission is the total removal of absolutely everything that could be conceived of as less than absolutely perfect. It thinks that by doing this, what you'll end up with is some kind of totally 'perfect self'. The perfect ego, a shining glory, the jewel in the crown.
It should be clear that the only ambition the ego really has is to get rid of you. The only purpose of the persona is to slice you up and separate you out and throw large chunks in the trash. What it keeps, it temporarily exalts like some kind of hero or savior or idol. But slowly it continues to find flaws in that idol, demanding even more vigorous 'purification' and sacrifice.
It says, well, if you give this up, and give that up, you'll be better off. It tells you you don't need all of what is, you only need the special good bits. But it doesn't tell you what happens if you take that to its ultimate goal. Keep going, and there will be nothing left of you. You'll live in a world where everything and everyone seems like your enemy, you are totally cut off and alone, depressed and frightened and weak, barely recognizing that you even exist, BUT .... drumroll... you'll have your perfect little fake self. Yay. And then you'll die alone.
So you can see... as you dabble even a little bit in being dishonest, inauthentic, not yourself, or trying to manipulate reality to get some kind of special value, special attention, special love... you're basically buying into a death trap. The temptation is you will indeed seem to get some special love, but.... it calls for a sacrifice. You've got to give up an arm and a leg for it. And then it's still not enough.
This is the promise the ego has for you. Go along with its plan for salvation, seem to achieve some kind of fake goal, or seem to find some kind of fake trophy, or seem to present yourself as some kind of ruler of the universe, and, in return, all of the rest of what you really are will be suppressed and attacked and gotten rid of.
Ultimately, the ego's perfectionism guarantees that NOTHING is acceptable. And sooner or later this will become apparent. Until you wake up and realize there has to be a better way.
You don't need a persona. You don't need an ego. You have God.
