When I was young, an elder in my tribe taught me how to stalk. One of the less obvious skills was a technique that he translated as 'splatter-vision'. Let's say we were exiting the forest, into a meadow. What I was instructed to do is to look at the horizon without focusing on anything in particular, just taking in all 180 degrees and wait for movement. When movement is detected, then it became time to focus on the movement and see if it was what I was stalking. If it is, proceed. If it is not, then return to splatter vision and wait for the next movement.
I found myself wondering last night if this technique is useful for mind. “Dinner was good tonight. I hope I see Mariah today. I have to get that project done for work by Friday. Watch out, there's a truck coming...” and then the focus: “WATCH OUT, THERE'S A TRUCK COMING.”
