I watched this video recently (https://www.youtube.com/watch?v=ROXqfjbIO-o) where Gary Weber and others talk about being non dual. For a video that calls itself 'the hard questions' it seems like it skirted an awful lot of practical questions. Lisa Cairns especially seems to say almost nothing.
I get that there are amazing mystical experiences that are possible including completely losing your sense of self, becoming one with everything. But these experiences can't persist beyond a short period of time. If you literally don't have a concept of 'I', as they claim, how do 'you' address an audience, recognise yourself on a passport and get yourself to the airport to attend a conference. I see that there are also great benefits from being calmer, letting your mind be quieter than usual, being more detached from emotion and experience coming and going. But still being a normal human being with negative emotions, getting angry or upset every so often, just less so.
Specifically I wonder about this non dual state
* is it present all the time? how do you do normal things without the concept of self?
* is there a gradual process of the ego/I dying down until it's no longer there?
* what is the role of thinking about 'I' and the self – obviously its not gone but how does one to relate to it?
