Riding the subway to work one day I saw a woman who was riding the express 5 train all the way uptown without leaning on or holding something for balance. It reminded of an old teacher I had. It also made me think of the difference between reef break and beach break. In particular the shifty sand bars most of us surf here.
A reef break is a study of experience over time as articulated through a breaking wave. So as different swell directions run through one learns about its behaviour. Where it bowls, what are the lines that can be drawn and this becomes the discipline.
Certain beach breaks seem to be about the absence of discipline. To embrace the spirit of this may hold some potential for drawing more workable lines in unpredictable conditions.
But this gets me thinking of the woman balancing on the subways of New York City. The train must shift in an irregular fashion. And to file the variations of each line at the different traveling speeds of the train would be impossible to index in the mind. But when falling into to a rhythm recognition must kick in.
It might do well in the line up to clear the mind and let memory recognize for itself.
