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 that 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.
