So as we take stuff from inside us, that we think we are, and we push it outside of us, this is us trying to get rid of ourselves. You're trying to get rid of what you are and to deny that you are it. And because you don't like the idea that you are guilty, which you believe is true, you will try to get rid of that guilt, which makes you get rid of yourself.
So you see, your identity goes along for the ride - shoveling out all the guilt shit from your mind and projecting it outward to disown it, makes you disown your self as well, because you've identified with it. So it's your identity you're trying to get rid of.
When you keep trying to get rid of 'that guilty self' by getting rid of the guilt (and you along with it because you're attached to it), you basically send yourself to hell and death. Projecting it keeps the guilt intact and you just end up getting rid of all of yourself. It's because you've identified AS the 'guilty self' that this happens.
You need a way to be free of the guilt without it being YOU that you are free of. You need to be freed from the 'guilty self' without it being your real self that is removed.
To do that of course we need two parts.
1) Correcting the belief that the guilt is true
2) Detaching from the guilty self and recognizing/re-attaching to your true self.
You can't detach from the guilty self while you believe that the guilt is the truth. You have to REINTERPRET THE MEANING that you've given to yourself. Guilt reinterpreted the meaning of WHAT YOU ARE to begin with, and now you need to RE-interpret the meaning of what you are to restore it back to its TRUE MEANING as given by God.
Once you can look at the guilt and recognize it is not the truth (in the light of truth/God/Holy Spirit), THEN you can detach what YOU are from IT and be willing and ready to genuinely let it go/detach from it.
This of course involves surrender of the belief in the guilty self and an opening up to your true/higher self/Holy Spirit's view of you.
