Non-duality is the ego's Dualistic attempt to resolve the paradoxes it creates. What is Duality and what is non-Duality IS Duality and Non-Duality is the opposite of Duality.

If there is no separation and everything is Brahman there is neither Duality or non-Duality, because Duality comes from separation created by the differentiated consciousness of ego/Ahamkara.

You were also making the distinction between 'false' self and 'true' self, so that is the creation of two 'selfs'. Where does that stand in relation to the 'whole'? Y'see Mike, the whole is a completely different discussion altogether and if people are talking about a 'true' or 'false' 'self' then 'whole' isn't happening.
