That took me on a discovery path of the philosophical approach to mindfulness. There seems to be a whole body of literature analyzing this from various angles. In particular, Varela seems to very influential. He is also cited in Daniel Siegel's book called "The Mindful Brain" (I was just referred to this book by a student of Psychology). Good stuff.

I wish mindfulness was based on some simple guiding principles/laws like with classical mechanics. But as with a lot of Biological processes, it seems to be a large complex system. Varela's "Theoretical Biology" book sounds interesting but I suspect it is a complex model of the body+mind rather than a simple one.
