Yin and Yang

in the study of opposites
the thought is of differences,
black and white,
night and day,
sweet and sour,
love and hatred,
good and evil,
and on, and on.
If running has strengthened my legs
and increased their size with muscle
then exercise to my physical body has done it,
if physical exercise is for the body,
then non-exercise is for the pyschological,
so that as the legs of a runner develop
in size and strength during exercise
so does the mind develop
in mental ability during non-exercise
or meditation and the contemplation of nothing.
