We must go down to the very foundations of life. For any merely superficial ordering of life that leaves its deepest needs unsatisfied is as ineffectual as if no attempt at order had ever been made.
The water itself is clear, but it is not being used. Thus the well is a place where only fish will stay, and whoever comes to it, comes only to catch fish. But the jug is broken, so that the fish cannot be kept in it.
This describes the situation of a person who possesses good qualities but neglects them. No one bothers about him. As a result he deteriorates in mind. He associates with inferior men and can no longer accomplish anything worth while.
Difficulties and obstructions throw a man back upon himself. While the inferior man seeks to put the blame on other persons, bewailing his fate, the superior man seeks the error within himself, and through this introspection the external obstacle becomes for him an occasion for inner enrichment and education.
