With energy manipulation u don't need to understand the different type of energy as long as you can manipulate them.
You told me that you wish to develop right? So i told you.
Everything that works needs some type of energy source.
Raw energy or pure energy isn't something you can find or decode from Google or an search engine.
Energy is all around us. It is the the person who absorb or manipulate energy to understand where it comes from.
... I can tell you but then it would be too much to take.
If you don't know what type of energy your taking in then it can alter the way you think and feel. You can change as a person all together. (I'm telling you from experience)
