If you pay attention for just five minutes, you know some very fundamental dharma: things change, nothing stays comfortable, sensations come and go quite impersonally, according to conditions, but not because of anything that you do or think you do. Changes come and go quite by themselves. In the first five minutes of paying attention, you learn that pleasant sensations lead to the desire that these sensations will stay and that unpleasant sensations lead to the hope that they will go away. And both the attraction and the aversion amount to tension in the mind. Both are uncomfortable. So in the first minutes, you get a big lesson about suffering: wanting things to be other than they are. Such a tremendous amount of truth to be learned just closing your eyes and paying attention to bodily sensations.
