We cannot talk with definition about our souls, but it is certain that we will decompose. Some dust of our bodies may end up in a horse, wasp, cockerel, frog, flower, or leaf, but for every one of these sensational assembles there are a quintillion microorganisms. It is far likelier that the greater part of us will become protists than a skyscraping dormouse. What is likely is that, sooner or later, carried in the wind and in rivers, or your graveyard engulfed in the sea, a portion of each of us will be given new life in the cracks, vents, or pools of molten sulphur on which the tonguefish skate.
You will be in Hades, the staying place of the spirits of the dead. You will be drowned in oblivion, the River Lethe, swallowing water to erase all memory. it will not be the nourishing womb you began your life in. It will be a submergence. You will take your place in the boiling-hot fissures, among the teeming hordes of nameless microorganisms that mimic no forms, because they are the foundation of all forms. In your reanimation you will be aware only that you are a fragment of what once was, and are no longer dead. Sometimes this will be an electric feeling, sometimes a sensation of the acid you eat, or the furnace under you. You will burgle and rape other cells in the dark for a seeming eternity, but nothing will come of it. Hades is evolved to the highest state of simplicity. It is stable. Whereas you are a tottering tower, so young in evolutionary terms, and addicted to consciousness.
