You certainly have more Vipassana/Buddhist practice than me. However, I want to stress that Mindfulness, in the general sense, covers all the (sensing) continuum physical/emotional/lower-mental/higher-mental, while body-scanning seems to concentrate on the first level. It is also not a static experience. (Real) Mindfulness is supposed to be a slowly transformative process, so I'm sure the observations you cited here will mutate (in subtle ways) as you continue the practice, and you grow as a person. > does anyone knows some science on this? “scientific” etymologically means “producing knowledge”. I consider (older) techniques like Vipassana as a form of (inwardly) empirical investigations that are capable of producing reliable (Self) Knowledge because they are (ideally) based on observation without judgment. I think it better to perfect that inner “observation without judgment” than accept some (outwardly) science (at this early 21st century stage anyway).
