Okay so yes, this is the next thing that I chose to teach you, what exactly are the parts of your energy system? Believe it or not, this is something really important to understand in energy work for things such as healing, understanding it can even make your overall energy work improve as well tbh.
Okay, so first off you gotta realize that each different races energy system is largely different, tho, that really depends as well, such as humans and human like creatures will be somewhat similar tho, there are always differences present. So don't think you know how every energetic system works just because you studied yours, etc.
Well yeah, let's get into it shall we? The first pretty universal part of the energy system is the energy pathways/meridians. These things are the well, tubes you could say that go throughout the energy system and allow transfer of energy very similar to veins. Humans, have one main one in each limb and they all connect to the main center one down the chakras. They also have a huge amount of smaller ones shooting off of the main ones throughout the rest of the energy system.
The next portion is Chakras, these are interesting things... They are generally where main energy pathways intersect but not always. All in all the functions they perform are really widely different per race. Elementals, hardly need them, Humans, need them to do energy work at all. For Humans they have a large amount of different functions per chakra.
Next off, the elements of your system.. Everyone has at least one or two or sometimes more elements in there energy system, whats the purpose of this? They basically align your system to specific properties/traits, so you'll be more so comfortable with those ones, and/or the same elements that you have. Tho, I also view it as almost like blood type, but, rather energy type you could say.
The final portion you actually need to know about is apart of your soul and ES, the Core. This is the portion that basically decides your race and performs a whole 'lotta functions, way more then anyone can really tell you. So say this core was destroyed, you would start going ghoul likely, tho, if safely removed you may technically just become the race of your vessel or well, human, tho... I also see race as being more so from the soul and the core just does some functions of such so I kind of doubt that you would really change that deeply, but that is just my view on it.
