Yes, sorry to drag jhana, etc into it. That wasn't my intention. All I was pointing out is that I don't think that it is accurate say that mindfulness is insight. As I understand it, it's one of the factors
for the arising of insight. I think that's an important distinction.
In fact, it could be argued that sati is also not something one can practise
in the sense of turning it on. One practises paying attention, which, with luck, leads to the arising of sati itself.
