I think, more accurately, the intangible thingie is the belief in that story/ego.
What I truly am is what I always am. What I think I am comes and goes. The intangible thingie is really just "what is". "What is" is the actual thing that I share with the five year old but the thing I think that I share is a belief. Then again the idea the five year old exists of ever did is just a belief to me now.
