soul, body, karma

souls - humans and most other conscious beings have, tho for many the connection from soul to body has been polluted by antimagic so in these cases these peoples' effectively soulless bodies act robotically and without true will

souls are metaphysical beings and therefore many influences from the evil forces of materialism attempt to invalidate them on the basis of being non-material, causing their associated physical bodies to disconnect (chemical-electrical mental processes still limitedly function - this is why the bodies still have animation)

it can be seen in people performing exclusively automatic activities based on the superficial worldly desires of money/material progress and toleration/survival of existence

people are of alien origin and souls are their true and immortal form - the bodies are physical temporary vessels for execution of karma,

realization and acceptance of this impermanance of physical is what connects a soulless/desouled body to a soul and allows the soul to shape itself through this enacted karma

when a souled body dies without having completed all of its fated karma the soul will be reincarnated into a new body to continue its journey

essence is similar to soul in that it is immaterial and eternal, but it is artificial and functional: goal is projecting karma rather than being directly linked with it and in this way essence directs Fate: of worlds and consequently souls,

in this case projecting karma is directly tied with Will

animals, plants, other native creatures to earth, and objects do not have immortal souls as human and many nonhuman people do, they however have spirits which are directly connected to the material world (can be indirectly modified by manipulation of composition through science and/or magic: alchemy)
souled and desouled beings of course also have spirits similarly

respecting these spirits is a component of karma, with intention being the distinction of its influence
