What exactly is noting in meditation?
Well, if you're asking because you've heard the word and don't know what it means, I'd recommend you to read my booklet on how to meditate.
That's the first thing.
But if you're meaning more philosophically or more technically, what is going on there?
It is the fixing of the mind and the straightening of the mind in regards to the object, reminding yourself
of the essence of the experience the reality of the experience as opposed to seeing it as an entity or a something a relation in terms of liking or disliking it or identifying with it just to experience it as it is
to remind yourself of what it is, because that's the word sati, mindfulness, we translate it as mindfulness, but the word sati means remembrance, it's the remindedness, the recollectedness, the ability to
recognize something for what it is and so that's what the noting does the noting is the creation in the mind of a recognition which is why the word is not which word you choose is not important but the word itself is an act of recognizing the object as close as possible to what it actually is
