Anders,

As usual, you have lots of great things to say.  But help me understand 
exactly what you mean by "level independent" consciousness.

Are you saying that if you have or experience some of that, then you 
know that it is fundamental, and can't be an abstract simulation at some 
abstracted or interpreted higher level?  In other words, if what you are 
saying is true, then that would be proof that our consciousness is at 
the fundamental level, and can't be at some arbitrary abstracted or 
interpreted level above that?
