One thing I never could make sense of in the Course was when Jesus referred to minds being joined or how it wasn't possible to be sick if minds were joined.
My ego could not understand this. It made no sense in terms of people being normal separate minds in separate bodies. I could only think in terms of doing something to something separate. How does anyone join with the mind of someone else in the first place? And why would that bring about the impossibility of sickness?
What I see now is that individuals in separate bodies are just fragments of a larger Self - the Christ Self, the One Son, and that identity has a single mind. There are not multiple Christs.
Mind, in its natural condition, is a single mind shared everywhere. It is the mind of the Whole Self. When pieces of mind seem to split off and be separate, that's because there is an illusion of separation happening. This separation is the root of all sickness.
Separation is two-sided, in that when the mind is divided, there is a piece of mind over here and piece of mind over there and they are kept apart by some kind of illusion of not being joined. That belief in separation produces sickness because it's a belief in limitation and lack. The separation blocks awareness, and blocks to awareness are denials which deny Life and thus produce death.
So when separation is present, and there are "two selves", that's a state of sickness. The mind is sick. It has multiple personality disorder. I'm talking about the one mind here, not an individual's mind. An individual's mind also is sick and divided within itself - each personality of the multiple personality disorder of the one mind, has within it further multiple personalities, lol
Ok so, to maintain the separation between selves, and thus to mantain sickness, both of those parts of the multiple personality must continue to exist. Without them being different from each other they would be one. If one of those two parts of mind decides to transcend what seems like the illusory limits placed upon itself, and redefines itself as the WHOLE, not a part of the whole, then it comes to experience Oneness with the other part of the mind, recognizing it as literally itself. Then there is only one mind. The two parts of mind are joined as One.
If the other part of the mind was trying to be an individual, it no longer can maintain that state of sickness because the first part of the mind has decided not to believe in it. So it doesn't have support for its belief and no matter how much it tries, it can't establish separation. If part of mind has woken up to the One Self (Christ), the other part has no way to remain in separation either. They must both wake up together to a single identity.
When Jesus woke up, He must have woken up to the reality that we are all One. And thus His awakening must have been the awakening of everyone. I don't know if this means that our minds MUST be healed, but certainly that it is POSSIBLE to be healed. If we were to decide to be one with Jesus, we would be healed instantly.
In the thought system of Holy Spirit, we are all one shared mind, and one identity. Holy Spirit looks upon CHRIST. Nowhere does it say he looks upon multiple real individuals.
When minds thus join, there is a healing of the separation between them. The separation defines their separate identity, so this must mean the undoing of a false sense of isolation and opening up to realizing that you are much more than you thought you were. An increase in awareness. Awakening. We awaken TO the Christ mind, the one mind, that we all share as the One Son of God. We're all the same Self. And this is how miraculous healing is possible.
