"The body is a tiny fence around a little part of a glorious and completely limitless idea. It draws a circle, infinitely small, around a very little segment of Heaven, splintered from the whole, proclaiming that, within it, is YOUR Kingdom, where God can enter not."
"Beyond the body, beyond the sun and stars, past EVERYTHING you see and yet somehow familiar, is an arc of golden light that stretches, as you look, into a great and shining circle. And all the circle fills with light before your eyes."
Let's draw a large circle and call it heaven.
Then inside of that circle, let's draw a smaller circle and call it earth.
You could say that the small circle overlaps with the big circle. In a sense, when you are in the small circle, you are in BOTH circles. As such, being in the smaller circle, or on Earth, it is possible to be aware of the fact that in truth you are ALSO inside the big circle. That you are always in heaven with God, even if you are dreaming of exile inside the small circle.
It's also possible while you are in the smaller circle, of focusing so much on the small circle to the exclusion of the big circle, that it can seem like ONLY the small circle exists. This is what being "blinded by perception of form" means, focusing on a limitation of smallness and not seeing the bigger picture. Focusing on the small circle and not seeing the big circle. Focusing on believing earth (small circle) is real, and not seeing the reality of the big circle at all.
But it is also possible for the small circle to be overlooked (forgiven) to such an extent that its boundaries become transparent and you become able to see the bigger circle behind it. As such, as you look toward the things in the small circle you will see the light of the big circle shining through underneath it. As though you are in two places at once. One foot on earth, and one in heaven.
Your perception takes on a temporarily parallel functioning, part physically focused on the small circle, and part spiritual-eye focused on the vision of the big circle. When seeing the big circle more clearly, the smaller circle is framed differently, and the things in the small circle become less important, less solid, less believable.
This smaller circle, when seen through, and when seen beyond, is regarded as the forgiven world, or real world. This includes the earth which is a small circle within the small circle. As mind becomes aware of its thinness and transparency, it simultaneously becomes increasingly aware of God, which is a very large circle beyond all small circles.
God is the big circle. This means the small circle is an illusion, because there can only be one circle. A separation is needed in order to imply that there is a second circle. Temporarily there seems to be two circles. But you cannot have two circles without opposition and conflict. With separation, the small circle is a dream of death, and without separation, there is no death because there is no small circle (no world).
At best, the small circle can be interpreted AS IF it is LIKE the big circle, as though reflecting heaven, and while the small circle persists you can seem to be in the small circle and mostly aware of the big circle at the same time. This makes the small circle seem less like an actual thing, and more like a faint illusion of a thing. It becomes less valued, and more overlooked. It seems more lovely, framed in the holy wholeness of the big circle, but is still a limited circle.
If you really want to go ALL the way to awareness of the big circle, you will have to transcend the small circle completely. You will have to go OUTSIDE the small circle, beyond its small reach, and beyond its limits. This isn't possible while remaining in any way inside the small circle, because the small circle doesn't cover all of the area that big circle covers. Also the small circle requires a belief in being separate in order to have a second circle. Without separation there is no small circle at all.
When you are ready to transcend the small circle and completely open up to the big circle, which is totally accepting atonement and ascending to heaven, you will transcend the small circle world and wake up in the big circle. At this point you will be completely aware of the fullness of the big circle, and there will be no small circles anywhere. In truth, only the big circle exists, and there is no small circle at all.
