It is as if you believe our human bodies are all wired the same, and it is our consciousness then that begins conflicting or working with it.
Interesting perspective... I would not have guessed that was the outlook some might be taking away from my writing as though it were my belief.
I might say, in contrast, that the hardware of our bodies are all fairly similar - and the differences come from the coding - which could be conflicted or harmonious.
Is it something best done simultaneously?
Not sure exactly what you're referring to here - you mean being both in the moment and stepping out of the frame to observe, simultaneously?
If so... I'd say perhaps in a sense, yes. Ultimately, one would probably want to get their processing power up to real-time analysis such that one can observe while being in the frame yet perceiving beyond it at the same time. T'is not exactly a straightforward path accessing such senses & abilities, however...
It's fun to think of such abilities. Someone practiced at this would be very quick and witty, I imagine.
