One thing common to all is facing sickness. Everyone encounters sickness
in their lifetime. Some handle it quietly with dignity. Others grieved that
somehow, they are falling prey to illness. Such behavior demonstrates lack of
understanding. Body not good listener, grows old and frail despite pleas of
desperation. It becomes sickly despite our efforts. Sometimes, affairs out of
our control. If we can come to terms with sickness, we can maintain peaceful
equilibrium. Opposite of yin of good health is yang of illness. These two are
connected by same thread that runs throughout Dao.
