Once upon a time in ancient Japan, a young man was studying martial arts under a famous teacher. Every day the young man would practice in a courtyard along with the other students. One day, as the master watched, he could see that the other students were consistently interfering with the young man’s technique. Sensing the student’s frustration, the master approached the student and tapped him on the shoulder. “What is wrong?” inquired the teacher. “I cannot execute my technique and I do not understand why,” replied the student. “This is because you do not understand harmony. Please follow me,” said the master. Leaving the practice hall, the master and student walked a short distance into the woods until they came upon a stream. After standing silently beside the streambed for a few minutes, the master spoke. “Look at the water,” he instructed. “It does not slam into the rocks and stop out of frustration, but instead flows around them and continues down the stream. Become like the water and you will understand harmony.” Soon, the student learned to move and flow like the stream, and none of the other students could keep him from executing his techniques.
