This is a rather advanced topic and I hope that you are prepared at least somewhat to look into this before you read this, as otherwise you might be confused as all hell to understand what exactly this is.
The mindscape or also known as the soul landscape is an area that you yourself, or others can enter that is a representation of your soul itself, as well as your mind, this is really interesting to say the least because of what you can see/do in there.
The soul landscape contains representations of your personality and such, it also contains what your soul itself is. Most people are easily identified to be human or not by simply viewing in for a second, and feeling what the “energy” in that area feels like.
Soul landscapes can also represent seals or binds inside of the person inside it, and via that area you can destroy them as well, which is very good for people to learn to do in the future. Seals/Binds can also be placed in this area.
But back to exactly WHAT it is.
Most people will be confused when they first read this, as a representation of your “soul/mind” makes no sense at the start. But let me tell you more-so about what it is. It is basically a “plane” inside your crown normally, or sometimes your core, depending on things. Normally it is your crown though. It is normally small and isn’t really a whole plane, just appears to be so. This is directly connected to what and who YOU ARE, if it’s damaged, YOU ARE DAMAGED, if you are damaged, it is, etc. If there is a seal placed there, then there will be a seal on you, etc.
