What I have come to further understand from the past 12 hours...

Thanks Vasistha for clearing that up. I could imagine if I were a wanderer from 6D, I'd want to help the 4D as much as possible, and that would be infringement on their own learning. So I'd have to return to home density. Or rather, I'd want to return. Still, we'll be able to watch over 4D, and those that repeat 3D. I can barely imagine the vantage point from which we will observe the lower densities.
