aka the chakra. I got a brief introduction to this by my naturopathic doctor who noticed that mine was huge. Since then I've gotten an abstract understanding of what this. It seems to be hard to describe in layman's terms. I can let it all go, or I can protect it. Sometimes I can't do this. It's a skill in development.
I think some "awkward" people just have a huge aura and don't know how to contain it, so they spew their energy onto other people and throughout the room.
But it's weird--I don't know if people will notice if they're not looking at you.
Does anyone know anything about this?
