Max,
First of all, I admire your search for the truth and investigating things from a perspective that makes COMPLETE sense...though our mind denies it
Now I am not trying to pick on you and I hope you dont get the impression that I am being a jerk

.....................but this is exactly what Steve explained as Subjective Reality (Advaita) in the podcast. You replaced consciousness with the word container. When you say consciousness to someone
they think its something outside somewhere else and this is because there are no objects defined in English language to understand consciousness. In SR terms consciousness is all that exists in the present moment including the physical body.
Container seems easier for people to understand because English language has a definition and so Container makes it easier for them to visualize. Just as you have mentioned that you are the container (including the body), SR says you are consciousness (including the body)....infact books on Advaita says that the body is an illusion and is not real....well I dont want to go there now.
I dont see any difference. Am I missing something??
