I just wanted to chime in about my perceptions surrounding elementals and devas. My perspective might not really fit in with some of the views already expressed here, but I wanted to share them for the record as we continue to put various pieces together.
Years ago when my clairvoyance was starting to open up, I became aware that people who had been smoking for years had a weird "fuzziness" going on in their aura around their throats and throat chakras. I could see an accumulation of debris that looked almost like tiny "bees" because they were swimming and moving, whatever these things were. And the things I saw looked kind of gray and nasty. I sort of filed this under, 'Things that make you go "Hmm."
Then over time I also noticed a similar kind of fuzziness, an accumulation of psychic debris of some kind, in the midsections of alcoholics, around the middle of the body and the back where the kidneys are.
And over time I noticed a similar texture of some type of low level attachment, kind of like a swarm of gook, around the sex chakra and abdomen of sex addicts and people who were addicted to pornography or going to strip clubs, that sort of voyeuristic sexual expression.
I also noticed a similar phenomenon with depressive and bipoplar types, only with them, the accumulation of debris was in a couple fo different places - largely over the heart, and usually the throat, and sometimes the third eye, too.
Okay. Fast forward many years later, when there was an interesting series of confirmations/explanations for what I'd been seeing.
Some shamanic healers and I were talking about what I'd seen and they told me that I was seeing negative elementals, elementals of a parasitic kind that had come into those people's auras and invaded the chakras in question (sex chakra, throat, etc.) because of the people being out of balance and in an addictive state.
And I also took some pranic healing classes, and in pranic healing there is a course called pranic psychotherapy which addresses healing negative emotional and psychological states. And what do they teach? That negative elementals accumulate over different chakras and organs when a person's aura has become weakened (through lots of negative thoughts and behaviors,) and when the elementals accumulate, they appear as a swarm of muddy-colored "bees" (my word, not my teachers term.) Clairvoyantly, though, that's a bit what they look like, like grey bugs swarming over that particular area of the body, feeding on it.
Now, we learned in that class how to use electric violet colored energy to expel the elementals and learned other techniques to heal and repair the damaged chakras. Just beaming it out of the palm to expel the entities in question and then using a simple hand motion called "sweeping" to clear the stuff out and dump it into a bowl of water mixed with salt. (The salt "traps" the critters, and afterwards you just put it all down the toilet. But I like to set as my intention that all the debris I'm dumping into the water be taken off to the Light rather than just dumping it into the sewer system. Sometimes I will use shamanic drumming, toning, or rattling as a sound vibration to help convey these energies off to a different dimension.)
And this technique or combo of techniques, I discovered, are very powerful.
When used on people suffering from various addictions and negative emotional states, expelling the elementals, clearing out the affected chakras and organs, and strengthening the auric shell (the egg surrounding the body that can develop cracks and holes, that's what allows negative entities to enter,) REMOVED the person's negative emotionality, their psychosis, their bipolar problems, their schizophrenia, their addictions - you name it. Because the elementals were no longer there feeding and exacerbating the need to feed the addcition.
Now, I'm simplifying the treatment a little bit, because what they don't teach in pranic healing (at the basic levels, anyway) is that you also usually have to expel demons from the addicted or depressive person, too. The elementals are a low level "bottom feeder" type of etheric parasite, but where they are found in large bunches, there is almost always one, if not a bunch, of demons as well that have attached to those affected chakras and organs. The demons can also be removed using divine electric violet energy. The deeper the person has sunk into addiction or illness, the more demonic attachments there are.
In private healing work, I've been able to "cure' people's depressions and addictions and mental illness through applying some of what I learned in pranic healing, some of the shamanic extraction and soul retrieval techniques I learned, plus some other stuff that has been revealed to me over time. The basic thing comes down to expelling the negative parasitic critters, including elementals, discarnates (there can be discarnate humans and animals attached to a damaged chakra as well,) and demons. And then you clear out and regenerate/purify the affected parts, and then you strengthen and clear out impurities from the auric field.
Now....the person still has to consciously give their permission to receive full healing. You CANNOT do this willy-nilly on someone because your work will be rejected and it will boomerang back on you, sometimes making you really sick. And also, a person can be completely cured and then welcome their illness back because they still, at a subconscious or conscious level, need their illness for some reason. (There are many complicated spiritual lessons and choices involved with illness.) A lifelong schizophrenic I knew was completely cured of his illness after I worked on him and remained cured for many months, able to finally go off his medications and function normally.
But you know what? He had been hearing these voices (of different discarnates and entities who were attached to him) since he was young, and when they were removed, after a while, he told everyone he MISSED the voices! He felt lonely without them. Sure enough, shortly after he expressed this to people, his schizophrenia came back.
This is why I don't run a healing clinic! What's the use of curing people when, deep down, there are real spiritual lessons involved with them KEEPING their illness! 
Complicated stuff! And a lot of people will tell you they want to be well, but what they really want is to figure out a path of healing for themselves, so they are not good candidates for healing. Every illness is a spiritual crisis of sorts. If people are aware enough to approach it that way, then they can often make it past the experience and welcome in true healing. But if you maintain exactly the same level of consciousness that you had prior to your illness after your illness, you will attract the same or a similar vibrational illness.
Anyway, I wanted to talk about that type of elemental - the low level, grey or dark, swarming critters that are definite parasites.
Contrast that type of elemental, which is "negative" in the sense that we experience that type as a parasite that is harmful to us - or at the very least, causes low level problems........
With nature devas, who are often called elementals as well.
I'd like to point out that, as I perceive them, these are different types of beings with very different consciousness.
Nature devas function as the "guardian angels" for everything in the natural world, from rocks to trees to bodies of water to the land itself.
Nature devas are not negative in nature. They are powerful, they are very different from us, and they are not "angels" in the way angels are assigned to help mankind grow spiritually. But they function as angels or guides for their various "charges" -- rocks, trees, etc.
Nature devas are the ones often called sylphs, ondines, gnomes, or salamanders, corresponding to the elements of air, water, earth, and fire. But in truth, the deviations and variations within the devic kingdom are much more varied than that.
For instance, there is a hierarchy within the devic kingdom. A forest at the edge of the property where we live has a forest deva who is a very specific, powerful being who functions as the "manager" of all the other tree devas in that long stretch of woods. Consider her an overseer who helps to steer the activities of the smaller tree devas. She possesses an amazing intelligence and is a wonderful ally who has told us much about the history of this area, later confirmed by people from this area. (Down to specific stuff about history here from the 1700's settlers, which I had no conscious way of knowing, and which people in the area confirmed later. Cool!) There has only ever been a relationship of honor, honesty, and mutual respect with her.
The nature devas honor anyone who attempts, in their own small way, to be "servants of the land," whether that person is just a gardener happily playing with his plants, a landscape designer creating beautiful spaces, or a psychic healer who works with correcting imbalances with the ley lines. All such people are considered "friends" to the nature devas.
If you don't seek a connection with the nature devas, they will generally ignore you, but they are NOT negative beings. They serve a really important function in their roles as guardians for nature, helping steer, correct, and balance the flow of energy for all natural things. Their work has been made incredibly difficult due to man's physical and psychic pollution. Interestingly enough, if you ask most devas which is worse, humanity's physical pollution through chemicals and the like or humanity's PSYCHIC pollution --- 7 billion people projecting chaos and negativity a lot of the time --- the devas will unanimously say it's the psychic pollution that's worse! They've never had to deal with psychic pollution of that scale before because this planet wasn't intended to accomodate 7 billion humans, especially at our current state of "awareness" (using that term loosely!
Now, in some powerful way that I don't entirely understand, the dragons are similar in energies to the nature devas, only they are not guardians of specific trees, rocks, or bodies of water as the nature devas are. And yet, dragons always proudly tell me of their elemental orientation as if revealing their true, most vital, essence. So, for instance, the primary dragon that likes to work/play with me is a red fire dragon. He tells me that this is because I need to learn to express fire energy more powerfully and appropriately, so his energies are best for me to work with. And if you look in my astrological chart, although I have some planets in fire signs, I also have a TON of stuff going on in air signs ( No wonder, right? I'm always full of hot air! . And air blows out fire. So within me I've always been aware of this struggle to try to assert myself in fiery ways, but then the air often cuts short whatever steam I've been building around a particular project.
When I can access the red fire dragon's contagious passion, laughter, and spiritual warmth, something lights up within me. I'm more focused, more able to communicate, more able to ground myself.
My honey has a green forest dragon as his helper, and since his career is as a landscape architect and land planner, and he grew up climbing trees and loving nature in a rural area, this energy seems entirely right for him.
So there is something very elemental about dragons that is related to nature devas (in that they seem to correspond with fire, air, earth and water energies) yet they are completely different beings.
I was meditating on this issue one night, how dragons and the elementals/nature devas might be related, and I had a gorgeous lucid dream vision. In it, I was standing up on the hill near our house, a powerful spot where the ley lines pierce through. It's truly a sacred spot. And I saw all of these dragons, in the various colors of the rainbow, all gently and silently landing around me. I saw a purple dragon, a white dragon, all different colors. And I felt that in this demonstration dragons were trying to show me something important. Like they corresponded not just with the four elements of nature (fire, air, earth, water) but also all of the colors of the rainbow. In some mysterious, fascinating way. Standing among the dragons in that dream was another one of those peak mystical experiences where I just felt awed and boosted in some magical way by the primordial, loving and positive, energies of these dragons.
So -- I have to say that in my experience you can't really lump "elementals" all into a negative category, saying that they have "fallen" or whatever.
To review, there appear to be negatively oriented, parasitic elementals that can be generated when a person is engaged in stuff that isn't good for him -- I've seen smoking elementals, sex addiction elementals, alcohol elementals, even electricity elementals. That's a big problem for us modern folks. Something about the way we currently generate energy puts out negative electricity elementals, so every time you are sitting by a computer for any length of time, also flourescent lighting is a big culprit because it also generates negative electricity elementals, your auric field is getting blasted with these. And I have a theory that it's a contributing factor for chronic fatigue in a lot of people. You can clear your aura of electricity elementals by taking a shower or bath or walking outside in nature, or just de-electrify or "power down" your space by unplugging every electrical device in the room and opening a window for about a half hour. It's also helpful to take a spray bottle and spray droplets of water throughout the room.
Anyway, there are also negative elementals that are generated by the lower emotions - places of war, bloodshed, or violence have hatred elementals (along with demons aligned with bloodlust) accumulated - even centuries after the violence occured. There are other types of negative elementals that seem to spontaneously gather at the sight of other human cruelty - sites where sexual predators have done their thing or acts of betrayal or nastiness have occurred.
But these are a different type of elemental than nature devas, which are creatures of purpose, beauty, and function.
The energy of a particular area does NOT get corrupted, in my opinion, by the nature devas. If anything, they are always at work trying to correct and to clear the energies that are generated by demonic forces and demonically influenced humans (or ET'.s) So you have a constant "battle" going on where the GOOD nature devas are trying to clear out negative parastic elemental forms that have overtaken certain spots. And you can see these entities working at cross purposes to each other if you tune in clairvoyantly or even just meditate on a spot and ask, "What's really going on here?" You'll be shown these complex, multiple layers of stuff going on.
And then you have dragonic energies, which also are a positive, elemental-related species of being, who somehow are also intimately connected with the four elements of creation, yet they are not negative in my experience. (Although, like I said, I've been warned about black dragon and I think he is aligned with chaos and demonic energies. Of course, chaos serves its own purpose, and in this reality/dimension, chaos serves a function, too.)
Anyway, I just wanted to try to lay out that we should probably be a little careful about lumping elementals into one "bad news" category, because they're not.
Nature devas are wonderful, and they can become great allies to you as you engage in spiritual work and also can help you to ground in a healthy way on the Earth to better fulfill whatever purpose you want to pursue here.
Dragons are somehow related to the four elements and also to the colors of the rainbow, so there is something very interesting going on with them. They are different from nature devas, and they are not elementals, yet they somehow self-identify with elemental (fire, air, earth, water) energies.
And then there are negative elementals, which seem to arise spontaneously (rather like maggots, I have to say, because that's REALLY what they remind me of when I see them swarming in somebody's energy field or at a physical location that has become distorted and corrupted by evil.) Negative elementals DO need to be cleared out , and where they accumulate in large numbers you will find negatively oriented human discarnates and also demons. The whole pack of them need to be sent of to the Light or sent to a higher place, and this can be accomplished through prayer, invocation, and also directing divine electric violet energy at the spot.
Whew! Thanks for reading to the end of yet another long post. Thanks for letting me share my views on elementals!
