Last night I used the below process, but in a different way. I did it VERY slowly. I re-stated each phrase several times over and really let it sink in before moving on to the next one. I actually found this to be quite powerful.
For example, in saying that I decided wrongly.. when I really dwell on that I come to realize that I actually DECIDED and I get in touch with that sense of responsibility and decision-making at having been the one who not only put in place this upset, but actually chose it myself.
There is tremendous power in getting in touch with your power of decision. Your decision making is not just a neutral act, it has power to it. It is causal. And I've also started to dabble in the idea of... .instead of just reacting to stuff and going along with it, instead, stopping and DECIDING... "I am" or "I am not" .... and feeling a kind of instantaneous change simply by making a firm decision.
I also inquired about the last sentence... letting Him decide for God for me. Jesus clarified that this really means allowing Holy Spirit to 'favor' or 'choose FOR rather than AGAINST' God, on my behalf. Allowing Him to favor God and to then accept His viewpoint. In this way, "for God" really means "towards God" or "in agreement with God". That made more sense to me.
"I must have decided wrongly because I am NOT at peace.
I made the decision myself, but I can also decide otherwise.
I WILL to decide otherwise, because I WANT to be at peace.
I do NOT feel guilty, because the Holy Spirit will undo ALL the consequences of my wrong decision IF I WILL LET HIM.
I WILL to let Him by allowing Him to decide for God for me."
It's also quite important to keep in mind the statement Jesus makes just prior to this prayer:
"But let me first remind you of something I told you myself. Whenever you are not wholly joyous, it is because you have reacted with a lack of love to some Soul which God created. Perceiving this as sin, you become defensive because you EXPECT ATTACK. The decision to react in that way, however, was YOURS, and can therefore be undone. It CANNOT be undone by repentance in the usual sense, because this implies guilt. If you allow yourself to feel guilty, you will reinforce the error, rather than allowing it to be undone FOR you.
Decisions CANNOT be difficult. This is obvious if you realize that you must ALREADY have made a decision NOT to be wholly joyous if that is what you feel. Therefore, the first step in the undoing is to recognize that YOU ACTIVELY DECIDED WRONGLY, BUT CAN AS ACTIVELY DECIDE OTHERWISE.
Be very firm with yourselves in this, and keep yourselves fully aware of the fact that the UNDOING process, which does NOT come from you, is nevertheless WITHIN you because God placed it there. YOUR part is merely to return your thinking to the point at which the error was made, and give it over to the Atonement in peace. Say to yourselves the following, as sincerely as you can, remembering that the Holy Spirit will respond fully to your slightest invitation:"
