Meaning:

Human life is like a rushing flood. It is difficult to stir up beautiful waves without encountering islands and reefs. Reality is this shore, ideal is the other shore, separated by a rushing river, and action is the bridge across the river. A person's value is determined by himself. The harder the flint is struck, the brighter the light it emits. Just as bad qualities can be revealed in fortune, so the best qualities can be revealed in misfortune.
