Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
If the king’s mind is fully controlled, all his family members and governmental officers are subordinate to him. His provincial governors present taxes on time, without resistance, and what to speak of lesser servants?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Angira Rsi asked the King whether his mind was also under control. This is most essential for happiness.
