But the question must be asked: Who, or what, is it that knows that consciousness cannot see consciousness?
It is intellect that knows this by analogy. Eye cannot see itself. And this is also known intellectually by questioning "Who will know the knower?" If we drill down to all layers of subject-object pairs, the query boils down to who is the subject of "I am"? Eventually, nothing else is there to fall back upon, only the awareness remains. This is the intellectual part.
This query, if meditated upon earnestly (by the ego-intellect itself), reveals that we are awareness itself. We are not the sense organs or the mind that are objects to an unknown subject, which cannot be known as other than self. And it is awareness itself.
Only this much I am able to say. Nothing further to add from me.
