I think, as has been mentioned by others earlier in this post, that attributing qualities to the self is not possible. As @abrakamowse noted, attributing ''I'' or ''Nothingness'' to that which is the recipient of perception cannot be done, for the self is outside of linguistic conception. The only thing one can truly say about the ''perceiver of perception'', is that it's there. It's of such a nature that you paradoxically locate it when you realize that you cannot point at it, or describe it's qualities. It is basically the empty, eternal space (properties attributed to it for illustrating intentions only) to which neurons send their message.
In the tradition of Advaita, as well as in the field of Indian philosophy as a whole, one of the main presumptions is that ''that which endures, is ultimately real'', or, more precisely, that that which is ''longer enduring'', carries a higher ontological status. Seeing as nothing in the manifest material world is permanent, and that the self allegedly is eternal, indivisible, unexplainable etc. It is revered as that with the highest ontological status.
