One observation made is, that you can't just jump straight into fear or guilt. It's not like you can go from innocence straight to feeling afraid, although it seems this is what we do because it can happen quite fast. There are steps that MUST precede it.
e.g. if you are afraid, you have to:
1) separate from love, 2) believe its really happened (sin), 3) become guilty, 4) feel compelled to fear punishment.
So you don't just 'get afraid', you have to have first done these other things. Similarly if you find yourself mainly in guilt, you didn't just become guilty, there had be these other steps before it (ie separation and sin).
Once you see where you are on the spectrum between love and death, ie:
1) Love/atonement/Holy Spirit
2) Separation idea
3) Sin (something really has happened)
4) Guilt (guilty for making it happen)
5) Fear (afraid of the punishment that guilt suggests will come)
6) Punishment (actually experiencing punishment)
... then you can figure out how you need to 'undo' the preceding steps. If you find yourself mainly in fear on an issue, figure out what guilt it was based on. If you are afraid, you ALWAYS have guilt underneath it. If you mainly find yourself feeling guilty about something - at least you haven't moved into fear, but now you need to realize there was some sense of 'sin' underneath it.
As you move away from the 'death' end of the spectrum you are moving away from the ego. As you move away from the Love end of the spectrum you are moving towards the ego.
You need to move yourself toward the atonement end of the spectrum if you want to be at peace. AND... this is the important part, you need to go ALL the way. You don't want to go all the way because the closer you get to it the more it challenges the ego's deepest-held truths (e.g. that the world has happened - which is a 'sin' idea). It also means getting up-close and personal with God which your ego does not want to do.
Many people (me too) get stuck in the middle of the spectrum somewhere around the fear or guilt areas, and think we need to just undo the fear or guilt, but really we need to look at what the guilt is based on, which is some kind of sin, then look at what the sin is based on, which is some sense of separation from God and yourself, and then undo even the idea of being separate, so that you can REUNITE with God and yourself in the At-one-ment.
At any time, all you need to ask yourself is:
1) Where am I at on the spectrum between holy spirit and ego?
2) Where do I want to be? (ideally, with Holy Spirit)
Then work your way one step at a time uncovering the foundation of where you find yourself.
