I walk on a path and follow it faithfully, mindlessly. I am trusting it to take me wherever I am going. Forward. An inevitable forwardness. So little effort required in this walking (because of the grace of good legs, good lungs, and solid ground). So little attention needed. The narrow path is clearly marked, the stones along its edges strong and sure.
There is relief here in this walking. What is there to think about? And then, perhaps a worry. I work through it in my head but it stays just as it was when it entered.
