Hi Kento
What makes you state that there is this "thing" behind the eyes?
Because the visual sense seems so dominant in my case.
When I close my eyes, the other senses have a chance to become more vivid. Then awareness seems to be wherever something appears: in the feet, the hands, in the hearing, or even the nose (when having partaken of too much mustard), etc.
But when my eyes are open, it's like the other senses have to take a back seat and the awareness is firmly there. This, subjectively, feels like being behind the eyes - I know there's nothing behind the eyes, but it's as if awareness has "parked" itself there comfortably, at least as long as the eyes are open and sight dominates.
When the eyes are closed and when hearing something it is like there's just the sound (and quickly on the heels of that the meaning appears). But with sight, there's always an element of this bodily limit that is perceived and divides this experience into something seen and something seeing. When I close my eyes this division disappears, not at once, but gradually. Early this morning I noticed there's an exception to this: when I lie in bed, the surface of the body is felt at all the contact points of the body with the mattress, yet then, too, there seems to be a head-bias in most physical positions.
When awareness is felt to reside behind the eyes, it actually feels empty behind the eyes. (I know this makes absolutely no biological sense; there's no experience of the retina, optical nerve, part of the brain, etc.) When the eyes are open, this empty space feels restricted to the inside of the head. When lying in bed, awake with the eyes closed (when there's also a head-bias), the empty space feels more limitless.
In the Goenka vipassana retreats I attended many years ago the basic technique was a form of bodyscanning, and then, too, the most detailed sensations could be felt in/on the head rather than other parts of the body. So even there, there seemed to be a head-bias.
Today, like yesterday, will be another +30°C (+86°F) day in Belgium. I'm asking: who is warm? For some reason, here it is very obvious that a judgement-thought is added to the sensation. The added judgement seems more like a natural reaction, a cause-effect thing, and for some reason doesn't seem to cause a strong "I"-flavour.
I'm more concerned about neutral experience where this "I"-flavour also seems to be present.
But in this case there's exceptions too. This morning, before it was hot, I was watching the trees, listening to the birds, some traffic in the distance, just sitting with a cup of coffee in my hand, not doing anything. At that moment, there actually didn't seem to be any "me" of "I"-flavour attached to anything, i.e. before I started reflecting and investigating if there was.
But when I started asking if this experience contained any trace/flavour/inkling of me, a certain intimate subjectivity seemed to be added to the experience. The previous awareness - which didn't manifest itself as anything - become a self awareness. This led to the absurd thought that it was my trying to find the "I" that was keeping the "I" alive.
So I'm continuing to notice and look into this "I" sense/flavour in various experiences throughout the day.
15 or 20 years ago, while staying at a Buddhist monastery in Thailand, a monk told me I had to let myself "die" (as the disappearance of the breath tended to take me out of concentration.) I thought it was meant as advice not to be worried about the disappearance of the breath, but now this advice pops back into my mind with some added connotations.
It must be tiring for you to read through these lengthy reports. I'm not sure if something is valuable or not, soI write it all down in the hope that you might spot where the hiding place of the illegitimate foundation of this "me" house.
Cheers
