Consider this example: You tell me to write a few lines, and while I am doing so you ask, “Do you feel something in your hand // notice a feeling in your hand // while you are writing?” I say, “Yes, I have a peculiar feeling.” ‒ ‒ Can't I say to myself when I write, “I have this feeling”? Of course I can say it, and while saying “this feeling”, I concentrate on the feeling. ‒ ‒ But what do I do with this sentence? What use is it to me? It seems that I am pointing out to myself what I am feeling, – – as though my act of concentration was an “inward” act of pointing, one which no one else but me is aware of, this however is unimportant. But I don't point to the feeling by attending to it. Rather, attending to the feeling means producing or modifying it. (On the other hand, observing a chair does not mean producing or modifying the chair.)
