I have to agree with what you said floriferous, the brain, body is not 'us'. Although I do not subscribe to the idea that we are all one consciousness. I feel on a deep level that there are many different types or types 'of' consciousness of which humanity interacts with but one.
Your disagreeing with my one point and my disagreeing with one of Lumazas points in itself raises an interesting point of discussion...
Ultimately, regardless of the question being asked, we don't truly know the answer. Through the lens of the mind we can only speculate. You might say
experience is an unfathomable mystery with more depth to it than our simple labels and descriptions could ever hope to convey.
Therefore, to label experience as a mystery allows you to let go of old beliefs and not form new ones which is infact a far greater position to be in than swapping old beliefs for new ones in the hope the new ones are better beliefs - they are still just beliefs and not reality.
In allowing the mystery of what is to encompass you, you can completely surrender old beliefs and not be weighed down with new (seemingly better) ones.
After all, the belief that I now have a better answer to a question than I did before is really just an act of appeasing a mind desperately in search of itself.
How are we going to see ourselves if we just bury ourselves in new beliefs? In a way this dillusional trap is worse becasue we now think we are spiritually more evolved with these seemingly better beliefs so we hold onto them even tighter. I used to be a Christian but now I believe in Buddhism or Sufism...it doesn't matter what we exchange our beliefs for - they are still beliefs and only ever will be no matter how much we search because the searching is only ever happening through the interpretive lens of the mind which can never know reality as it is.
It is something we all do but perhaps should investigate more.
