Here on earth we carry a body made of bones, muscles, arteries, and so forth. Then, after death, we acquire a spiritual body, formed out of our moral qualities. A good man acquires a moral body radiating with beauty; a depraved man a moral body radiating with evil. This is formed while we are living backward. Our spirit-body, however, is only partly formed out of that which is now joined to us. Whereas one part of the spirit-body received by us in the spiritual world is formed out of our moral qualities, the other part is simply put on us as a garment woven from the substances of the spiritual world.
