TERMBASES
When things reach their extreme, change occurs, after
the change they evolve smoothly, and thus they continue for a long time. This
notion comes from The Book of Changes and is a way of
understanding the principles of change. According to this text, things are
constantly changing and will, when they reach their extreme, develop in the
opposite direction. People ought to understand the way of change, look for the turning point when things reach their extreme,
and facilitate change so as to effect their smooth and long-lasting
development.
