Great posts Kaj Sotala. Would it be wrong to say this is an attempt to place Buddhist/meditation insights in the domain and language of cognitive science? I would suggest that an exciting step would be the connection to neuroscience - just recently read Michael Pollan's 'How to Change Your Mind' and became aware of the concept of default mode network, and how its down-regulation is associated with states of flow and likely with meditation/psychedelic induced changes in the perception of self. Interesting stuff!
