If you want to know more about residual spiritual energy, then just be aware of the fact that you also have spiritual energy inside you.
The way it works is like this;
Spiritual energy is like water, in normal human bodies it stays inside the physical body because that is where the spirit is anchored to, and as such
your emotions are magnified by the spirit because of it's symbiotic existence with the physical world.
When the body dies, there is no longer and boundary for the spiritual energy - it becomes like a gas, free to float about in the air without much
However when that spiritual gas comes into contact with something physical, like a wall, it either collects on the wall or simply disperses.
Hench why some mediums occasionally put their hand to a wall in order to glean insight into the events that unfolded.
However, the interesting part is when two different spiritual energies come into contact with one another - in this case your 'positive' energy and
the deceased's 'negative' energy.
I spoke earlier about the human body containing the spirit, and i'll go into that with a bit more detail;
Your skin is like a semi-permeable membrane, very similar to the skin of any other living organism, or the surface of water, and as such 'spirit
force' can enter and leave your body quite easily.
Now, if you're like me, you'll probably be horrified at figuring this out - with so much spiritual energy in the world compared to your meagre
reserves one seems vulnerable and susceptable to spiritual violation.
But that isn't how spiritual energy works.
I compared spiritual energy to water and gas earlier, and like those two states of matter they can mix with one another.
If one is more concentrated (like that of the spiritual energy found at a crime scene) then it will be difficult to deal with, However
You are still living, and as such you still have the capacity to alter
that energy with your own.
Well, that's pretty much all i know about the subject, and most of it is done through my own musings, so i wouldn't take it too seriously (but you
You'd be better off finding an actual medium, i'm just an amatuer.
All you need to do is learn to recognise that yes, it's a very dark and foreboding spiritual residue that has been left behind, but it isn't going
anywhere, and it isn't going to do anything bad to you so long as you are capable of recovering from it.
It's as natural as keeping yourself clean, in a way.
