Educational Q&A

Even after achieving political success, a ruler’s highest obligation is to safeguard Dharma—just order and righteous conduct—because it yields the greatest welfare, including in the hereafter.

In the Śānti Parva’s counsel to the post-war king, Vyāsa addresses Yudhiṣṭhira: having fulfilled kṣatriya duty and gained an unobstructed kingdom, he must now preserve Dharma through righteous governance.
