After death, our ruling affection or love awaits each one of us. This is never rooted out to eternity because our spirit is exactly like our love; and (what has not been known before) the body of every spirit and angel is an outward form of her or his love that is completely responsive to the inner form that is the character and mind of that spirit or angel. That is why you can recognize the quality of spirits from their faces, their postures, and their speech. That is why our own spirits are recognized in this world if we have not learned how to pretend with our faces and postures and speech. We may gather from this that our own eternal quality is that of our ruling affection or love.
I have been allowed to talk with people who lived more than seventeen centuries ago, people whose lives are known from the literature of their own times; and I have been convinced that the same love they had then is still sustaining them.
We may also gather from this that a love of wealth and the usefulness it affords also remains with us forever, with exactly the quality it acquired in this world. There is this difference, though: for people whose wealth served them as means to useful lives, it is turned into delights in keeping with their usefulness, while for people whose wealth served them as means to evil activities, it is turned into filth—filth that they enjoy just as much as they enjoyed their ill-used wealth in the world. The reason they enjoy the filth is that the foul pleasures and pursuits that were their practices in the world, and their greed (which is a love of wealth with no thought of use), correspond to filth. Spiritual filth is nothing else.
