I was thinking about rising through the Spheres of the Planets tonight, and the image of a spark came to mind.
You know, bonfires, they shoot out sparks. The sparks rise up high into heavens before they burn out. A little tiny ash floats back down to the earth. Every bit of it that could burn is consumed.
So we've got seven planetary heavens, right? And under the lowest, the Lunar sphere, hanging off the lowest edge of heaven is the Elemental sphere of Fire, the highest and purest form of matter. Below that is Air, and below that Water. At the bottom is good old solid Earth, the most material of material realms.
And here's this spark. It's sunshine and minerals from the earth consumed in the release of all that energy it absorbed while it was alive. As it goes through its final transformation, it shoots up through the aethers aiming for heaven, using the heat of its own combustion to get higher, and leaving behind a husk of itself to drift back down to earth, empty of all the power and effort that went into creating it in the first place.
So, neat stuff. I don't like ham handed mataphors, but I do seem to have a habit of using them myself.
