The hypothalamus is involved in the filtering of sensory data and the data showed that the sensory floodgates were basically widely open.
Right. Very interesting. More and more of this research is coming out showing that the brain structure is altered in advanced meditators. The obvious question for me is - how far does this different brain wiring go to explaining experiences such as non-dual awareness and so on.
I find this almost revolutionary. It means for me that genuine reality is way beyond brain-based experiences. Any thoughts held onto or view held on to or experience held onto is not really the final point. Any explanation as to what it is or maybe is not definite either. The difference between a normal being and a buddha seems to be that the normal being takes the contents of brain-based experience to be true regardless of how refined or 'open' they are whereas the buddha does not. Buddhas seem to have awareness as an 'adornment' as a natural consequence of going beyond the way a normal being operates.
I am pretty sure that Sakyamuni had a brain, just like he had a heart, lungs, liver, spleen, kidney, etc.
. His enlightenment was not brain-based. Also all of the tantras etc have not been transmitted by 'beings with brains'. Interesting.
