The whole world gets filtered through any of the beliefs we have, including the belief in the idea of I.
Consciousness filtered through belief in I
So when there is this belief in the idea of I, usually placed on our human self or parts of it, this also filters how we interpret - and perceive and experience - consciousness.
If I see I as this human self, separate from the rest of the world, then consciousness appears to be a property of this human self. It is a human consciousness, and it is my consciousness. It is unique, and is born and dies with this body.
This is a natural view when there is an (exclusive) identification with our human self.
Consciousness filtered through I as awareness
When the sense of I shifts to awareness or consciousness itself, the experience of consciousness also shifts. Now that is who I am. It is not a property of this human self, rather, it seems that this human self is a property of consciousness.
Before, this consciousness was interpreted as arising from this human self. Now, this human self - and the rest of the world of phenomena - clearly arises within consciousness.
I am the seeing, I am pure awareness, timeless, spaceless, formless, and the world of phenomena, time, space and form is Other, it is the seen.
At some point, there is the dawning realization that here too is there a polarity of I and Other, now placed on seeing and seen. Where is the boundary, really? What is the difference between the two? Maybe the experience of this form of I and Other also comes from an overlay of ideas, maybe this too is filtered through a belief? What is already more true in immediate awareness?
Consciousness absent of I
This exploration allows the final belief in the idea of I to be seen and fall away. Now, consciousness arises without the filter of I and Other, and seeing and seen is seen as consciousness itself. The content of awareness is awareness itself. It is all form and emptiness, Ground as seeing and seen, and there is no I inherent anywhere - not in the seen and not in the seeing.
The same consciousness appearing in different disguises
The very consciousness that initially appeared as my human consciousness, as a property of this human self, and then as seeing as opposed to the seen, is now revealed as Spirit, as Ground, as Buddha Mind, Divine Mind, as seeing and seen, and inherently absent of I anywhere.
It is all revealed as the very same consciousness having appeared in different disguises. And the disguises were only created by beliefs, by attachment to ideas, filtering how it all appeared to itself.
