(For some reason, I can't access the first post from Astan to click on and quote from, so I'll do this a different way:)
"There is a lot of talk about consciousness which is beyond body, feelings, thoughts, etc." -Astan
I don't think Consciousness is
beyond body, feelings, thoughts, etc. Rather, Consciousness is the
essential nature of those things (of all things). In other words, every thing owes its existence to Consciousness... Every thing arises in and is essentially made from Consciousness. Consciousness is not a separate entity that's
apart from the body, feelings, thoughts, etc.
"I understand the idea that we are not a body and feelings..." -Astan
Yes, we are no more the body and the feelings, etc. than the sun is its rays... or the ocean is its waves... or the sky is its clouds...
"If I leave the body, the feeling, the memory and the thoughts, what will be left?" - Astan
You/Consciousness is left.
Just as, if you take away the rays, the sun is left... If you take away the waves, the ocean is left... If you take away the clouds, the sky is left.
But, I do get what you're saying. Who wants a continually cloudless sky? or a continually wave-less ocean? or a ray-less sun? How boring would that be, right?
Well, good news: it's not an either/or situation. It's both/and.

Knowing yourself as Consciousness doesn't
exclude the experience of the body, feelings, thoughts, and all the things of the world. This knowing
includes the experience of all those things, of every thing!
