Qestioner: Why do you say that non-duality means ‘there is only you’? For me it makes more sense to say ‘there is no you’?

Tom: Yes, many people say it the way you do, but there is a specific reason why it is said in the traditional scriptures that ‘only I exist ‘ or ‘only you exist’ as opposed to ‘there is no I’ or ‘there is no you’.

The ‘I’ or ‘I AM’ is being pointed out as indicating the reality.

Why is this?

It is because only when we turn towards the ‘I Am’ or the Subject can the non-dual reality be intuited. Otherwise, as you say, the knowledge remains only on the conceptual level for the ego-mind. This is more fully explained in Chapter 8 of The Path of Sri Ramana.

I also explain this more here.
