First you start by thinking that you need to forgive others. That's not true, because everything you think is about them is really about you. Taking back your projections undoes this error.
Secondly you think that you need to forgive yourself, because it's all about you. But this still relies on the belief that you really sinned. Undoing the belief that you're a sinner leads you to a third insight.
You cannot forgive yourself, really, because you have not really done anything that needs to be forgiven. For you to be forgiven means you must now open up to a forgiveness which comes from God, to accept the Atonement. That you are forgiven because you DID NOT do anything wrong.
That means that God already recognizes that you did not really sin at all and nothing happened. That's not so much something you can do to yourself, as it is simply something you must allow to be true and accept.
At first that seems to be true beyond yourself, because it is God's truth, but gradually the two will become one.
So really you cannot forgive others, and you cannot forgive yourself, and you don't need to. What you ultimately need to do is to accept the Atonement. In the atonement, it is a state of pure forgiveness, which sees that there is nothing to forgive and there are no real sins.
Once you get your mind into that perspective, that everything you THOUGHT you did that needed forgiving has actually NOT HAPPENED, then it's merely a matter of ACCEPTING that you are ALREADY forgiven. Haha!
Therefore it is true that at NO TIME EVER is there a real call for forgiveness or a need to be forgiven, because God has never believed that you are capable of real sin, because there is no real sin. You are forever innocent.
Then you can enjoy the relief, celebration and joy of recognizing that God loves you, you are worthy, you are innocent, you are free, and then you can allow Holy Spirit to undo ALL of the consequences, effects, symptoms and manifestations of your faulty belief.
If you truly BELIEVE fully and strongly that you are forgiven because you have not sinned, and that therefore you cannot be sick and have no need for defenses against the truth, you WILL act to cause all signs and symptoms and "effects" of your wrong decision to be undone, and you WILL demonstrate miracles to reflect and prove that the Atonement is your truth.
True healing is the recognition you have never been sick (sickness is not real).
True forgiveness is the recognition there is nothing to forgive (all is forgiven).
All of the other "steps" in your forgiveness process - the withdrawal of projection onto others, the taking responsibility for having been the one who did this, etc are just stepping stones leading up to the truth. The truth that you are FORGIVEN ALREADY, and that you just need to accept this is the truth about you.
Ultimately then forgiveness is not needed and does not "happen". All of the process of "undoing" is just a preparation of your mind, a purification, allowing you to see and accept that. You can call it a forgiveness or "applying forgiveness" if you want to. But really it is preparation for accessing the truth that you are FORGIVEN and God loves you, and He never stopped.
As the miracle principle says, "miracles are everyone's right, but purification is necessary first". This purification is the preparation for accepting the atonement, which entails great honesty and willingness. When this purification is accomplished, THEN you can access "forgiveness", which is a single unified state of VISION In which you see only that there is nothing to forgive. Then you are miracle minded and the miracles will flow to demonstrate your TRUST that God's truth is true.
All is forgiven!
