Before the separation, let's say you were wholly Christ, you were everywhere, and you looked upon yourself and saw yourself everywhere.
Then the separation came along and put a "rift" down the middle of you, separating you from the other half of yourself, like a deep wound.
The other half of you remained in Heaven, but this half of you seemed to believe in the split and saw a wall keeping you from yourself. You couldn't see through this gap that formed, because it looked like a solid wall of sin.
That wall is this universe. Physical matter is that wall of sin. This world is the content of the wound. It is the world of attack and pain and misery and death attempting to convince you that you are separate from yourself and God.
As you awaken, you gradually learn that this wall of sin is not really there, the universe doesn't really exist, and you start to look past its illusory forms and obstacles. To heal the world, is really to heal the world away, so that it is Christ who is healed, and the world-shaped wound is undone. Your vision begins to see through it, like it becomes transparent, as if the mists are clearing and you see beyond the veil.
Eventually, you start to catch a glimpse of Christ, which seems to reflect back to you from across the gap, and the gap diminishes in this sight. You are starting to see the reflection of yourself, or rather, the other half of you. You see this by not seeing the wound any more, and forgetting the world that arose in your madness.
As the gap closes, swallowing up the entire universe in its going, and disappearing into nothingness, Christ's Vision is finally healed, the wound is fully undone, and there is a wholeness again. In this wholeness there is no gap, no separation, no rift, no world, no bodies, no images, no forms.
There is only Christ looking upon himself once again, just as the Holy Spirit loves to do, sharing His vision. The wall of sin is gone, invisible. The planet has faded into nothing. And all that remains is the Heaven God created. The Son of God in all His glory.
