How comfortable is time/space?

But then isn't that also source? So it doesn't stay there for eternity the energy is reborn is it not? To start again?

Depends how you look at it.  

This is all just my opinion based on what I personally intuit as truth, but if you were to ask "8th density" what is going on right now, it would say, "nothing".  From that level, it wouldn't recognize our reality as existing at all.  At least, not in the way we think it does.  From that "level" there are no levels.  There is no distortion there.  You are still in 8th density right now.  We all are, as one.  What we interpret as reality is an abstraction, or distortion, of this primal unity that is 8th density.

It's like we are dreaming at night, having all these seemingly fantastical events, seemingly interacting with separate parts, or having a nightmare.  And then we wake up.  Oh yeah!  We were never in any real danger, we are still safe in bed, in 8th density.  We were just having a dream of distortion.  No distortion actually happened.

So the only thing getting reborn is our focus, as we take another nap and dream another dream.  8th density is the source and container for all existence/experience.

Another analogy is this world is sort of like a block of marble.  Say you carve a statue out of that block of marble.  You might even say the statue was potentially inside that block of marble the whole time, we just had to get rid of all that was not the statue and poof, there it is.  8th density is like that block of marble.  Pure potentiality, but rather than chip the "extra pieces" away, it is more like we just "forgot they existed" or stopped perceiving them.  So we put some perceptual blinders on ourselves, and voila, the illusion of separation appears to exist. So the 8th density block of marble now appears to be a 7th density statue (which contains the 7 density levels of a given octave).  

All the other bits are still there, we just can't see them for a moment, until we wake up.
