The constant agitation of our thinking minds, which we encounter so vividly in the meditation practice, is actually fed and compounded by our diet of television, radio, newspapers, magazines, movies and the Internet. We are constantly shoveling into our minds more things to react to; more things to think, worry and obsess about; and more things to remember, as if your own daily lives did not produce enough on their own. The ultimate irony is that we do it to get some respite from our own concerns and preoccupations, to take our mind off our troubles , to entertain ourselves, to carry us away, to help us relax.
But it doesn’t work that way. Watching television hardly ever promotes physiological relaxation. Its purview is more along the lines of sensory bombardment.
(…)These observations and perspectives are merely offered as food for thought.(…)There are no ‘right’ answers, and our knowledge of the intricacies of these issues is always incomplete. They are presented here as examples of our interface with what we might call world stress. They are meant to provoke and challenge you to take a closer look at your views and behaviours and at your local environment, so that you might cultivate greater mindfulness and perhaps a more deliberate and conscious way of living in relationship to these phenomena that so colour and shape our lives, whether we know it or not, whether we like it or not.”
