Question: Does ‘awareness’ or ‘consciousness’ have a source, eg. is the actual brain organ the source of all manifestations and sensations? Or is consciousness primary and the ground of existence?

Tom: I don’t know the answer to that question. I only know about ending suffering. When suffering ends, one could say that all there is is consciousness, as this is the undivided experience, but this is only an experiential truth, not a scientific one, and so your actual question remains unanswered.

I wrote an article on this topic while back, feel free to take a look: Is everything really consciousness?
