I am not going to be concerned with being attentive, but i am going to see what is inattention. I am watching inattention, and i see i am inattentive most of the time. So i am going to pay attention to one thing at a time, that is, when i walk, when i eat, i am going to walk, eat with attention. I am not going to think about something else, but i am going to pay attention to every little thing . So what has been inattention becomes attention.
So i am now watching inattention. That is, i am watching that i am not attentive.
