One of the great things about hiking down into the Grand Canyon was how absolutely focused one becomes.
The great dissembler and attention grabber of our age, The InterWeb, is cut off essentially as soon as you descend beneath the Canyon Rim. I suppose one could bring a radio into the Canyon if desired, but I have no idea if there would be any reception and frankly, those that descend to the Canyon floor are not those likely to be concerned with such things.
On the hike - down, across, up - one's attention is 100% consumed by the here and now. Partially, of course, this is due to the fact that one is engaging in an activity that requires all of one's attention. It is not like just walking down the sidewalk at home; a mis-step is a potential risk and could result in serious outcomes. It also due to the fact that when one takes the time to stop, one just drinks in the amazing natural wonder of what is all around one, 360 degrees of amazement.
One is completely lost in the moment. There are no distractions. There is no "breaking news" or text or e-mail notifications that demand immediate attention or 1001 siren calls of interest to divert us. There is only the trail and the beauty and the meal at the end of the evening and the stars at night.
There is focus. There is engagement. There is 100% being in the now, without any distractions to attention or involvement.
Contrast this with the way I go through life normally: I am constantly focused hither and yon of incoming bits of information. I turn from e-mail to text, from text to chat, veering over to news or to something that demands my immediate attention. I am not here; I am not really anywhere. I am merely bouncing from incident to incident, an information and task responder without focus.
I have included the Yamaoka Tesshu quote before; I included here again now as a reminder, mostly to myself. I want to find if the water is hot or cold; I must accept that my focus on nothing else but drinking the water at hand to find out if it is hot or cold.
