This is really why our sense of separation from God is riddled with guilt, there is an aspect to it of shock and horror and not realizing what we've done. We then seem to have some awareness of the results of what we've done and it seems like we must've made a terrible mistake, and therefore we are now horrified by ourselves and are afraid.
What's needed to escape this isn't so much to admit to guilt. Guilt can't be admitted to. There can't be a total admittance of truth at the same time as guilt existing. You can admit to being innocent, but you can only deny being guilty. And the only solution to being guilty is to reclaim innocence. Owning up to guilt, if you were to do it, would just hold the guilt against you and make you suffer. This is why we don't want to do it. Deep down we know we just made a mistake and that we didn't mean to.
"Forgive them father, for they know not what they do."
It's hard for me at times to admit to 'what I did' even if what I did was an accident, because that means owning the guilt. If it were possible to admit to something without being guilty, that would be easier. But nobody wants to own guilt. It is counter-productive. We should want to get back to innocence, as a true atonement, rather than say "I'm really guilty". Owning guilt doesn't atone for anything. To the ego it atones because the ego wants to find someone to blame and to keep the guilt, but to the Holy Spirit we are always innocent.
Is regret healthy? Is a guilty conscience helpful? Should we suffer in remorse? How long is enough time to be ashamed? How much suffering is enough to atone for a sin?
The ego wants us to own up to 'really doing stuff' because this makes the error real and doesn't forgive it. Holy Spirit asks us to be forgiving, to overlook error, and to demonstrate that it has had no effects. To demonstrate that we and the other person are innocent because nothing has really happened. The ego doesn't want this, because then it can't find anyone guilty. It takes practice.
Do you have the right to claim innocence and to choose to relieve yourself of all guilt and return to innocence with Holy Spirit? And what if someone else doesn't believe you deserve it yet?
We need to all remember that if we find someone else guilty it doesn't prove that they are guilty, it proves that WE are guilty. We can't find someone else guilty without us being involved, no matter how convinced we are. If the other person is truly the separate guilty party, then we should remain in perfect innocence. And if we remain in perfect innocence, we will see perfect innocence in the other person, so we won't be able to find them guilty. It's not possible to find someone guilty without including ourselves. That kind of puts a damper on the ego's parade. We MUST forgive otherwise we ourselves cannot be forgiven.
