Shloka 20
Daṇḍanīti and the King as the Cause of Yuga-Order (दण्डनीतिः राजधर्मश्च युगकारणत्वम्)
यात्रामाज्ञापयेद् वीर: कल्य: पुष्टबल: सुखी । पूर्व कृत्वा विधान च यात्रायां नगरे तथा
yātrām ājñāpayet vīraḥ kalyaḥ puṣṭabalaḥ sukhī | pūrvaṃ kṛtvā vidhānaṃ ca yātrāyāṃ nagare tathā ||
毗湿摩说道：“有才有勇之王——身健、兵强、资用充足——当先立妥当之部署，尤须巩固本城与国土之守备，然后方可下令出师。内境既安、备具既成，乃可依审慎之治国用兵之道而伐敌。”

Educational Q&A
A ruler should not rush into war: he must first ensure readiness—especially the security and administration of his own capital and realm—and only then order a campaign, acting from strength and proper provision rather than impulse.
In the Śānti Parva’s instruction on royal duty, Bhīṣma counsels the king on when to initiate a military march: after making prior arrangements and safeguarding the city, the king may command the army to set out.
