It is important to understand that our energy is not static. It doesn't just glow around us like some kind of painted halo. Our energy is engaged in a constant exchange with the energy of the world around us. Our auras are more like a candle flame than you might imagine. Like the flame, they constantly radiate energy outward, and that energy is dispersed into the world around them. For the candle, there must be some kind of fuel, such as paraffin, to sustain combustion. However, the flame would not burn without additionally taking in a vital component from the atmosphere surrounding it: oxygen. Through this interaction, there is a constant exchange going on that feeds the candle flame even as it sends its heat and light out into the world. So it is with us, a constant and dynamic exchange. We are sustained by the energy naturally generated by our bodies, yet even as we are constantly radiating energy outward, so too are we taking energy in to continue the cycle.
A candle flame warms the air around it with its shed energy. We affect the world around us with our energy radiation as well. Spent energy constantly disperses from us, being shed in the process of our burning. This energy drifts off of us, settling like psychic dust in the subtle world. This trace of our passing will linger for some time until the energy is picked up by one of the currents of the subtle reality. Once it gets caught in one of the eddies or floes, the energy is moved and agitated, reduced to a neutral state again, and eventually recycled into the greater whole.
Not all of the energy that we leave in the world around us is simply cast-off detritus. Some of the energy fingerprints we leave on objects and places are imprints that we very actively put there. By attaching special significance to certain places or things, we actually invest some of our energy into that location or object. Whether we are conscious of the process or not, the more attention and emotion we focus on something, the deeper an impression that we leave upon it.
Think of it like this: a candle lit in an empty room will burn regardless of whether anything is there to receive its warmth and its light. However, a flame can also be used to warm someone's hands, or it can be used more directly on an object, to burn a mark into it. How close something is to the flame and how long it is exposed to its energy determines how deeply it will be burned. Some objects we merely scorch with our personal energy, but some things we practically brand with our individual signatures. A Memory Ghost Let us say that your grandmother has passed away. You've inherited her house and a good portion of her personal effects. Sad, but a little excited to be gifted with such tangible memories of her, you move in. You have one of her rings resized so you can wear it as a constant reminder of what she meant to you in life. You are very happy in your new home, but after a few weeks, you start noticing things that seem a little strange. For instance, every time you walk past the kitchen, it seems like you can see your grandmother standing over the stove. You catch the image just out of the corner of your eye, and of course when you look directly at it, there's nothing there. But it seems like her presence lingers in the kitchen, even when you can't actually see her. You also get a strong sense of her radiating from her favorite rocking chair. This is so strong that you unconsciously leave the rocking chair empty, almost as if you're expecting her to sit down in it at any moment. And sometimes, when you're sleeping, you wake up all of a sudden, and it seems like your grandmother is hovering over you, watchful and protecting. You can't see anything in the darkness of your room, but the sense of her presence is almost palpable.
In this case, it is very likely that there is no ghost and your grandmother has already moved on. The feelings and impressions that you're picking up on in the house are simply lingering echoes of your grandmother's energy. In the kitchen, for instance, she was always cooking, and a special way she expressed her love for her family was through her desserts and her food. It follows that a great deal of her energy was invested into the kitchen, and this energy residue is strongest near the stove. The rocking chair was somewhere she sat when she needed to think and ponder the direction her life was going, so of course a lot of her energy still lingers here as well. And whenever you wake up at night with the feeling of your grandmother's presence nearby you, the ring of hers that you now wear is sitting on your night stand. If you really think about it, you realize that the impression of her presence is actually coming from the ring itself, a piece of jewelry that she always wore, for as long as you can remember.
We leave little echoes of ourselves in the places and objects that are important to us. Sometimes, we are half-conscious of this. For example, if we want a close friend to have a reminder of us, we often give them some piece of jewelry or some little object that was very precious to us. We usually even give it with the words, "Keep this close; it will remind you of me." The reminder is not simply in the gesture of giving the gift. We could just as easily go to the store and pick out something expensive. But some of the most precious gifts we give to others are things that we've had with us for a while, things that we've attached a great deal of sentimental value to. Why? Because our energy is all over these things. When we give this to someone, we are giving them a piece of ourselves, and that energy, unique to us, will radiate out of the object, constantly reminding our loved one of what it feels like to have us near.
It is possible to for us to leave traces of our energy on objects or places without having that energy resonate with our personal presence. Strong emotions can very easily imprint themselves on the world around us.
Emotional residues, like our psychic dust, build up over time. Unlike psychic dust, however, emotional residues can linger for quite a while. Since we tend to associate places with the emotions we've experienced in them, we have a habit of experiencing the same feelings in the same places over and over again. The pre-existing energy of the place only encourages this, and so it creates a self-perpetuating cycle of emotion.
For example, a teenager almost always retreats to her room for sanctuary from the "unfair" world. Whenever this young person has a bad day at school or has an argument with her parents, she takes all her hurt feelings with her to her private space. Now, her original intention is to simply find some place that is separate and away from those things that seem to always be hurting her. And yet by constantly taking these bad feelings into her personal space, she imprints the negativity on the very walls. Over time this builds up, and it becomes a self-perpetuating cycle of negative emotions.
Given the tumultuous energy of a teen, this cycle can get pretty intense. Before too long, her room has become a kind of emotional pit, where anyone walking in can just feel the angst and anger dripping off the walls. A little bit of this negativity rubs off onto anyone exposed to it, inspiring similar emotions which then feed back into the pre-existing residue. Like breeds like where emotional residues are concerned, and every time the lingering impression inspires that self-same emotion in a person, that person's emotional energy feeds back into the residue, strengthening it. So, whenever her parents come up to her room to comfort her, they find themselves instead inspired to a confrontation. They wind up yelling and arguing even more, unaware that a large part of their feelings are being influenced by the general feel of negativity radiating from her room. In such an atmosphere, it's almost impossible not to react to the ambient emotion.
Negative emotions often leave the strongest lingering impressions, but not all emotional residues inspire bad feelings in people. We can invest objects with very positive impressions as well. Consider that favorite teddy bear you had as a child. You carried that thing with you everywhere, and for you it was the ultimate talisman of safety and security in an unpredictable world. When you went to bed at night, you knew beyond any kind of doubt, that that bear would protect you from all the monsters under your bed. You lavished love and attention upon it, so much so that it almost seemed to take on a personality of its own.
It is possible for enough energy to be invested into a residue that it takes on a life of its own. This process is very rare, but it can still happen with unintentionally. More common, although still far and few between, are intentionally created energy constructs. These are sometimes called elementals by witches and magickal workers. Another term for them is "astral construct," because they exist entirely in the non-physical realm.
An energy construct, is created purely out of energy. It has no real existence in the physical world prior to or after its creation. It can be tied to a particular physical object, or even a place, but this serves as a focus only. The real existence of the construct is in the subtle realm. Such constructs are born of a continuous build-up of focused energy - either the energy of strong emotion, or the equally potent energy of a person's intentionally directed will.
