Lightgigantic: It is when we are caught up in trying to understand things, instead of looking from our direct experience what reality is, that we miss the oneness.
There are no parts to this oneness. If there is a part then we are still identifying with the thoughts that are arising of a separate me.
If people are still philosophizing about non-duality then they are not looking at what is being pointed to.
Non-duality is not spirituality, it is not a thought system of any sort - what it is telling us it that we are all ready that - and THAT is unchanging. What in us never changes? Our body certainly does and so do the thoughts that arise. That which never changes is the knowing of everything that arises - that is irrefutable and it is ineffable, indistinguishable, unknowable. You know that you are - more correctly - the knowing is there always and it is the same knowing that has always been there - everything that appears appears in it - and that knowing is not separate or broken up in any way. It is continuous.
Any distinction between the absolute and one's self, as you put it, is only in the thought. The distinction is arbitary and dependant on conditioning. Does thought though mean there is a definite separation? Isn't it only thought that seemingly separates because we have all agreed to categorise all life matter with words? And, is the word ever the actual?
In the indigenous Australian population, there is no word for time. Could that not mean, therefore, that time cannot exist for them given that they do not have a word for it? Could time be merely a mind construct and not a reality? The reason I raise this point is to show that we assume separation just because we have a word for something, but these words are abitrary and created. It is like we have a universal agreement about words - we agree to call stuff this and that - but does that mean just because we agree to name something that the word is capturing the actuality of what really is?
Non-duality is not a philosophy. Look and see what is when words are not being used to describe, look for yourself instead of assuming the truth of the reality we all describe.
