in terms of the metaphysical descent of consciousness, Desire was the first big consequence of self-awareness ie individuality born out of the seperation of consciousness/causation itself. The jinns being described as 'fire' was not islamic theology per se, it was already existing arabic cultural terminology adopted by islam. it was symbolic fire. The jinns are the seraphs of the bible. you can read up on this, iblees was a seraph in muslim understanding.
Desire is something unquenching, hence, if it finds itself rooted into an eternal persuit ie 'The Absolute God' then that desire takes consciousness all the way, hence 'man was created to WORSHIP ALLAH', worship being the object of desire itself. in terms of our metaphysical ascent, this is where the astral experience of pure LOVE takes over and unites all consciousness. This is the positive side of the jinnat/seraphs and also our own astral nature. It is called Chandha in buddhism, 'wholesome desire'. Whereas when iblees came face to face with the physical form, Adam, his attention was taken away from the Absolute persuit and then it became destructive fire, envy/hate etc. this is called Tanha/craving in buddhism. Hence the nature of the seraphs from the highest ranking 'angels' into 'burning serpents'.
within that, ie his attention being lost easily, was because he didnt posess balance of te yin/yang energy, he was a yang entity. the desire plane is the right brain/active/yang. jinnat are not logical/left brain/passive beings by nature. the worship of God from the jinns, is not in terms of bowing down to God, it is more like seeking God, an active persuit. Being forced to look 'down' to the physical world whilst lacking the left brain/logical side means the jinns do not posess the right understanding eg of laws, of right and wrong. as soon as they mix with the material world, they fk up and turn satanic UNLESS they are controlled, kind of like dogs...by people. it's a destructive/burning fire that has to be controlled and that's difficult.
we also posess that feiry nature within us along with the logical thinking side and hence posess more understanding and can control jinns by controlling our own desire. easier said than done mind you.
Fire elementals, are linked to the 4 physical elements, earth, fire, air, water which are linked to the 4 seasons, so it is somewhat subjective. they have nothing to do with the astral. they are etheric. the etheric plane ie Allah 'breathed' the spirit into man, the same applies to the physical world, it is conscious due to the etheric lifeforce. the good elemental spirits are in turn vicegerents of that lifeforce in terms of protecting the elements. the demonic ones, are destructive in that regard. something of a yin/yang aspect to this live brahma and shiva in hinduism. i mean destruction is normal in the cycle of life and death, so are they really 'demonic' or is that just the subjective human interpretation?

it was actually fascinating the first time i read up this stuff because i literally grew up around a little culture where our elders strongly believed in such things..and my grandad who im a lot like, used to have direct experiences...he obv opened his third eye (what they call 'cutting the veil' in our culture) and could see it.
