When you are eating, eat. When you are going for a walk, walk. When you are reading, give your attention completely to that, whether it is a detective novel or a magazine or the Bible or what you will. Give your complete attention. Complete attention is complete action, and therefore there is no, ‘I should be doing something else.’ It is only when you are inattentive that there is the feeling that you should be doing something better. If you give your complete attention when you are eating, that is action. So what is important is not what you are doing but whether you can give total attention.
