To be aware of inattention

Attention is this hearing and this seeing, and this attention has no limitation, no resistance, so it is limitless. To attend implies this vast energy: it is not pinned down to a point. In this attention there is no repetitive movement; it is not mechanical. There is no question of how to maintain this attention, and when one has learnt the art of seeing and hearing, this attention can focus itself on a page, a word. In this there is no resistance which is the activity of concentration. Inattention cannot be refined into attention. To be aware of inattention is the ending of it: not that it becomes attentive. The ending has no continuity. The past modifying itself is the future - a continuity of what has been - and we find security in continuity, not in ending. So attention has no quality of continuity. Anything that continues is mechanical. The becoming is mechanical and implies time. Attention has no quality of time. All this is a tremendously complicated issue. One must gently, deeply go into it.
