It is known through memory of education at school, but that would just be direct experience of memory? Staying with the direct experience of seeing with no memory, there isn't that.Haha yes, and on a conventional level of course this is known. But how is this known? Staying right in direct experience…
It's like a windscreen,Look at whatever is in front of you. It is seen from the perspective of two windows (eyes) or is it like a windscreen view? Now zoom back in and try to find the thing that’s seeing. Is there seeing separate from what’s seen, or is there just what’s seen?
There is just what's seen. there is the feeling of being someone, and somehow, this feeling is often confused as being "the one doing" the seeing, but it makes no sense that a feeling could be doing that.
there's just the experienceIs there any awareness separate from experience or is there just experience?
No it can't.Again can this be known without a thought of a different experience?
I like this metaphor!Let’s say that you have lost your keys and you swear that you left them in your coat. You go to look and check all the pockets - the keys are not there. You swear they must be as that was the last place you remember them. You have a vivid memory of putting them there after you left the house. But when you check they are not there. At this point you can keep believing that the keys are in your pocket, or you can admit you were mistaken. This is just like that. You may see clearly that the self is an illusion but still feel a sense of self - just like the keys. But feeling something to be true and seeing that it is or is not is different.
the more I try to pin down/locate the sense of self, the more I try to objectify it, then it comes in different flavors: sometimes it's like an imaginary film/border around my body, sometime it's like a small ball inside my chest, sometime it's just a vague feeling with no precise location, kinda "floating around".Keep the focus of attention on the sense of self and inquire:
Does the sense of self have a location?
Does the sense of self have a shape or a size?
Does the sense of self say or communicate anything?
If the answer is yes, how does the sense do this exactly?
Does the sense of self have any characteristics or attributes?
What is the sense of self ‘made of’? An image? Sound? Taste? Smell? Sensation? …Thought?
It does not say or communicate anything, it's just a feeling of believing in a "me". It is often linked with the desire to find/resolve something.
It is made of a mental image (a small ball in my chest or a border delimiting my body), often interlocked with the sensation of it and a vague, wordless thought (synonym of sensation?) of it.
