A Course in Miracles might seem like a self-study where you do certain prescribed steps and have your own willingness and wake up all by yourself.
But, Holy Spirit has other ideas.
He is not only willing to help you, but is capable of helping you, in ways that are beyond what you can do for yourself. Including supernatural ways, ways of healing your mind, emotions and your body. Things which all by yourself you are not equipped to accomplish or even understand, but which are still possible in spite of your inability to comprehend it.
I think that as you become more willing and open and surrender more ego, instead of it being all bout what your ego does to become spiritual, it becomes more about what you're willing to accept and receive and allow, and this opens the flood gates for Holy Spirit/God to come in and help you.
Your development of trust in God allows you to become willing to operate in God's gifts, to extend those gifts, and to receive them for yourself and others.
Holy Spirit isn't a Holy Bystander, although His perception is uninvolved with the ego. He recognizes our beliefs and illusions and overlooks them and leads us into the light with True Empathy. But this also means, besides Him lifting you up into the light, that He can reach into your illusions and work on them with you. He can heal them, and all forms of separation, including death. Let's also remember that Jesus was raised from the dead BY the Holy Spirit.
Welcome Holy Spirit into you. Invite Him in. Encourage Him to enter by being willing to surrender, relax, let go, and trust to receive His helpful support and healing power.
I was having, or was going to have, a big release as part of a healing that I wanted to "get over with". However, upon being willing to start to release it, Holy Spirit came in and said "you don't have to suffer" and started to heal me, draining and disappearing those feelings as they were coming up.
Often I also now find that if I am upset and need to cry, at the instant that I become willing to cry and let it out, Holy Spirit steps in and suddenly starts to clear it for me. No tears come out, but the issue goes away. Holy Spirit asked, when I was wondering why the heck He kept doing this, "would you rather cry?"
You don't have to do this all yourself, and you don't have to suffer, and you don't have to put up with symptoms, and you don't have to even go through all of your unhealed pain all by yourself. What a relief!
"Holy Spirit will undo the consequences of my wrong decision if I will let Him."
This is very powerful and important. The consequences of your wrong decision, whatever it may be, is whatever came from your belief in separation. Self attack, denial, emotional pain, physical sickness, disability, mental illness, whatever. Holy Spirit CAN and WILL undo all of those 'symptoms of separation' - the alleged consequences of sin - the "real effects" which your belief in sin produced. IF you will let Him, and to let Him, you have to develop trust in Him and in allowing Him to operate in and through you.
You have help! Use it.
