"Now that you understand what the Outer Soul World is, let's get on to the second one, True Soul World.
The True Soul World is the place where your consciousness enters when you say you're visiting the Soul World. Inside of it, there are the things that define you, the 'real' you.
As there are different types of showing the True Soul World, for example your stars. Just like them, everything else manifests inside your True Soul World, techniques, laws, etc... You got my point.
The True Soul World also exists as a barrier, to block other Souls from intruding you, just like me. Though, I somehow succeeded, don't ask me how, because I simply don't have any idea."
