Seconds before, our deck had been full of squirrels scavenging for sunflower seeds. They disappeared. I walked into the kitchen just in time to shout "Fox!" to Bill at the kitchen table.
The fox was in no hurry, so i fumbled with my smartphone-camera and snapped a couple of photos before the fox disappeared into the shadows of the forest.
If we are foxy in our meditation, we can catch those dagnabbit distractions before they lead us into completely forgetting our meditation object.
One possibility is to open the lens of awareness wide. The squirrels who disappeared had wide-open awareness, which told them to skedaddle because danger was afoot.
With wide-open awareness, we can catch the distraction before it catches us. Otherwise, our mind goes trotting off into the woods.
