This is a short introduction of our knowledge about the energy of the soul. We will call it Fire of the Soul here, because it is the easiest way to explain the energy. Every being that we all know, be it on the physical or non-physical plain has that fire. A incomprehensible energy that comes from the Creator itself.
This energy, is very much a will. It's will to involve; a will to allow change, are seemingly alike of flames that change on different kinds of fuel. For that example we will use two colors to explain your plain and ours.
The physical beings on your plain are blue flames, hot flames. Flames that are unpredictable. Even though most of us have had centuries to perfect the skill of seeing, we are not able to tell everything about your blue soul-flames, nor do we want to. This flames are also unbelievable passionate, in such a way that it can end quite miserable. That passionate part of the soul, is exactly that, that enables the physical to be physical. It takes quite a lot of energy, to fit a will into a body.
In a process that we will call Soul-merging, the emerging of a soul to a body, is what makes you different from anyone of the non-physical plain.
The non-physical plain, has decided for one reason or another, that they are happy as the yellow, less passionate flames. They have grown out of the phase that is needed to grow on a physical plain. Or just do not allow the flame to get that heated, the lower the flame, the more yellowish it is, and the more the soul has trouble with Soul-merging. It is just to low burning to use the energy and merge it into another form.
It is seemingly alike with metal, it has to burn on a high degree, and lower than that it will not become a liquid and it can not be forged. A physical soul has the ability to forge something out of it's energy. It goes farther than even being with physical body. It means that you can forge a whole life, it is of powerful use.
The ones that do not forge are more like candles. Beings that try to light the way. They shine little light's across the darkness and give different perspectives on situations. It is not important to use lot's of energy in the candle, it is simply possible to shine brighter if needed and allow the candle to be nothing more than a little scorch.
When two of this souls connect through the light they both have access to. It will be felt. Some have such a lot of energy, that it allows the soft burning of the non-physical to burn with the physical, which means a form of communication. It is that fact that when people are in the Power, it means that they can hold onto their energy, strong enough that they don't tire to much when a non-physical is using it, to mingle the soul-flames for a great message.
It is also the reason why some of the non-physical can not keep up to long, before the fuel is gone and they need to separate again. On occasion it is possible to fuel each other, which can allow a longer conversation and gives a greater effect to the healing of the flames of the physicals.
All in all, it is important to sit in the Power, that allows the fuel to remain inside the physical, even though it is used by the non-physical beings.
