Bhagavad Gita, Chapter 3, Verse 20

By action alone did Janaka and others attain perfection. So, with a view to guiding others, you too should perform action.

People in a position to be watched carry a weight beyond just their own choices, others are quietly taking cues from them.

King Janaka is held up here as proof that fulfilling real-world duty and genuine spiritual depth aren't opposites. Krishna points to him as a working example, someone whose action itself became a teaching.
