Somehow I don't feel in a hurry to move to the final questions but would rather allow things to unfold in their own time.
That is fine.
One thing that makes me hesitate is that I'm not sure categories of existing or not existing are quite the right language to talk about experience.
Assuming you mean that what we refer to as 'I', 'me' does not exist, then this 'I' is more of a mental phantom.
'I' is a thought. If you take some items, say 'Table', 'Community' and 'Santa Claus', then 'table' is an item that exists. 'Community' is trickier, as it points to a general thing that exists, a concept rather than something specific.
'Santa Claus' points to something that doesn't exists, but everyone talks about him. Just like 'I', 'me'.
Search for Santa? None is found. Search for an 'I', 'me'? None is found.
If I try to describe what I have experienced it seems to require poetry or paradox.
Language is itself non-dualistic. It needs objects and concepts to work. It breaks down at the point when discussing absence of self. The only words one may use are those that 'point' to what is real, rather than describing it.
All language is a pointer anyway, as the Buddah said 'The finger pointing at the moon is not the moon'.
There is no doubt that there is a continuing experience of unfoldment, physical, mental, emotional taking place through the dialogue I have been having with you.
Oh yes, and this will continue. There are no starts or ends of anything.
I will let you comment and then ask you the final questions. There is no hurry in answering, but this will effectively finish the process and may just tease out any areas that you are not clear on.
