“In order to remember unity you must, in a sense, travel back to it, undoing as you go all you have learned since last you knew it, so all that remains is love. This undoing, or atonement, has begun – and once begun is unstoppable and thus already inevitably accomplished.” (C:19.19)
We are said to travel backward in time, rolling up a metaphorical long carpet, until we arrive at the place where separation occurred (or seemed to occur). Each part on our journey without distance must be undone–each individual part. And then we will be back to Oneness, Oneness with God, Oneness with our Christ Self, awake in Christ-consciousness, occupying the elevated Self of form.
The ending is certain, and the atonement, or undoing, has begun for all of us reading this now, for we would not still be reading if we had not asked for the journey to begin. When we go backward in time, we are returning to love, and in that return is the everything that we have wanted. Love gives us all that we really want, and the closer we get to the end of journey, the better we will understand the truth of this. Atonement is unstoppable, and for this we ought to be grateful. Though we are prone to endless procrastination, and we may wander from the path, we will inevitably return, for free will sets the limits on miscreation. We cannot forever stay apart from God, for this would actually counter our real will, which in truth is one with His Will.
The undoing does not have to be complex, though it is usually so experienced, especially before the elevated Self of form is sustained. We have gotten ourselves so tangled up in our minds, perplexed by egoic notions of separation, that miracles are needed to save us. And those miracles are forthcoming. We can walk into the light at any time, though God Himself decides the exact moment. If we love completely, we are, in a sense, already there; we are having a glimpse of Christ-consciousness, and this glimpse, this satori, will sustain us until sustainability is actually achieved.
