That's the basic assumption.
Separation from what ?
As-if "to exist, existing" and Existence Itself are separate entities.
Religion, birth, physicality, materialism, cause/effect ..... all imply a creator and a separate creation.
Reality ..... and a virtual really ...... "virtually" reality ..... an image, likeness, not not original , TOTALLY REALITY. TOTALLY REAL.
There is only The ONE ONE .... no matter the name of ONE ..... that ONE name is The ONE .
ONE is ONE ..... ONE SELF WHOLE BEING
"So ..... what about the narcs, disease, the manipulative manipulators, all woeful woes, the ills of the world.... all that seems contrary to all the other contraries ? What about "my world and my loved ones, my broken weak and dying body. All my ceased loved ones ..... what about all those years gone by, all those people dead , what about ..... what about this very question about what's it all about .... what about cause and effect and all the other assumed powers? "
I stick with Truth ... what IS .... and only The ONE/IS ... IS ... THIS HERE NOW.
The very idea of separation or departure to/from ISness .... just doesn't fly.... it's no idea at all.
It's like asking "who by taking thought can separate/alter the very thought that is this thought ? "
