Usage Context
Used to encourage a developer of character or to explain why someone survived a difficult period while others failed.

The 'shaking earth' represents sudden environmental crises—financial collapse, war, or personal loss. The 'stable house' is the person who has invested in their character (Iwa), their community ties, and their spiritual health during periods of peace. It teaches that you cannot build a foundation during the earthquake; the quality of your life is determined by the preparation you did before the ground moved.

Used to encourage a developer of character or to explain why someone survived a difficult period while others failed.
When the earth shakes, only the stable house remains. Character is the only protection against the 'tremors' of life. Your stability in the storm is a result of your labor in the sun.
