ELEMENTALs are considered to be character spirits.
There are a lot of mythology and folklore around the subject of elementals, often going into great detail about them. I’m not sure that amount of detail is really necessary myself.
A simple answer would be that elementals are intelligent, self-aware entities made from the essence of one the main elements of life, earth, air fire and water.
Some supplies consider them to be of a completely different ‘race’ to humans. I think they may belong to the angelic realms as they aren’t of the physical world, or the spirit of someone who has passed from it. I’ve spent time giving this subject some consideration and I believe that the angelic hierarchy exist at a more progressive level of consciousness, beyond the spirit world and consists of Elementals, Devas, Angels and Archangels, each with advancing consciousness.
Elementals are invoked for magical purposes and protection rituals and are most traditionally one of the following:
gnomes (earth), undines (water), salamanders (fire), sylphs (air)
Some supplies also list, pixies, fairies and elves as elementals.
There are also character spirits called nymphs, often classed in the same category as elementals, but truly considered to be slightly different. While elementals are the essence of an component, a nymph is the spirit of something. Examples of nymphs are dryads, and naiads. Dryads are tree spirits, each tree has its own spirit, or each dryad has its own tree to care for. Naiads are spirits of freshwater.
Existing above the elementals and nymphs, at a higher evolved consciousness are devas. while a dryad would be considered the spirit of a tree, its deva would be the guardian of the complete forest – almost like a team leader I suppose. Other devas protect holy sites, mountain ranges, shrines, and places with magical or mystical qualities.
While some people claim to be able to see elementals, I do surprise, if it is simply a way for us to translate the energy, or life essence that runs by character when we are aware of it, or a way for the strength of character to make itself known to us. As humans we can’t always put into words what we feel, so we need a way to make sense of it all, and in ancient times, stories were the way this was done. Stories used to describe character’s essence may have become mythology over time and now that is how some expect to see the energy, so they do. Just a thought. Or maybe elementals do exist and are hiding out in our very gardens, ponds, forests and flows.
