The reality of this kind of correspondence of everything in heaven with everything in us has been shown me by a great deal of experience—by so much, in fact, that I am as convinced of this as I am of anything that is so obvious as to be beyond doubt. There is no need to append all the evidence here, though, and there is too much to include. The reader may see some included in Secrets of Heaven where correspondences, representations, the inflow of the spiritual world into the natural, and the interaction of soul and body are dealt with.
Even though we completely correspond physically to all of heaven, we are still not images of heaven in outward form, but only in inward form. Our deeper reaches are receptive of heaven, while our more outward ones are receptive of this world. To the extent, then, that those deeper reaches do accept heaven we are heavens in least form, in the image of the greatest; but to the extent that our deeper reaches are not receptive, we are not heavens or images of the greatest. Nevertheless, our more outward aspects, which are receptive of the world, may be in some form that is determined by the world, and therefore in more or less beauty. Outward, physical beauty has its origins in our parents and from our formation in the womb, and thereafter is maintained by a general inflow from the world. This is why our natural form differs markedly from our spiritual form.
I have been shown at times what a spiritual person is like in form, and I have seen that in some people who were lovely and attractive in physical appearance that inner form was misshapen, black, and grotesque—what you would call an image of hell rather than of heaven; while in some who were not beautiful, the inner form was graceful, radiant, and angelic. After death, our spirit looks the way it actually did within the body while we were living in it in this world.
