"Avoid watching [TV] programs and commercials that assault you with a rapid succession of images that change every two or three seconds or less. Excessive TV watching and those programs in particular are largely responsible for attention deficit disorder, a mental dysfunction now affecting millions of children worldwide. A short attention span makes all your perceptions and relationships shallow and unsatisfying. Whatever you do, whatever action you perform in that state, lacks quality, because quality requires attention.
"Frequent and prolonged TV watching not only makes you unconscious, it also induces passivity and drains you of energy. Therefore, rather than watching at random, choose the programs you want to see. Whenever you remember to do so, feel the aliveness inside your body as you watch. Alternatively, be aware of your breathing from time to time. Look away from the screen at regular intervals so that it does not completely take possession of your visual sense. Don't turn up the volume any higher than necessary so that the TV doesn't overwhelm you on the auditory level. Use the mute button during commercials. Make sure you don't go to sleep immediately after switching off the set or, even worse, fall asleep with the set still on."
