Mindfulness is nonconceptual awareness. Another English term for Sati is
'bare attention'. It is not thinking. It does not get involved with thought
or concepts. It does not get hung up on ideas or opinions or memories. It
just looks. Mindfulness registers experiences, but it does not compare them.
It does not label them or categorize them. It just observes everything as if
it was occurring for the first time. It is not analysis which is based on
reflection and memory. It is, rather, the direct and immediate experiencing
of whatever is happening, without the medium of thought. It comes before
thought in the perceptual process.
