vārtāmūlo hyayaṃ lokastrayyā vai dhāryate sadā |
tatsarvaṃ vartate samyagyadā rakṣati bhūmipaḥ || 35 ||

[paragraph continues] In consequence again of royal protection, men can everywhere sleep fearlessly and at their case without shutting their houses and doors with bolts and bars. Nobody would hear the evil speeches of others, far less actual assaults, if the king did not righteously protect the earth. If the king exercises the duty of protection, women decked with ornament may fearlessly wander everywhere without male relatives to attend upon them. Men become righteous and without injuring serve one another because the king exercises the duty of protection. In consequence of royal protection the members of the three orders are enabled to perform high sacrifices and devote themselves to the acquisition of learning with attention, The world depends upon agriculture and trade and is protected by the Vedas. All these again are duly protected by the king exercising his principal duty. Since the king, taking a heavy load upon himself, protects his subjects with the aid of a mighty force, it is for this that the people are able to live in happiness. Who is there that will not worship him in whose existence the people exist and in whose destruction the people are destroyed? That person who does what is agreeable and beneficial to the king and who bears (a share of) the burden of kingly duties that strike every caste with fear, conquers both this and the other world.
