Shloka 19
Daṇḍanīti and the King as the Cause of Yuga-Order (दण्डनीतिः राजधर्मश्च युगकारणत्वम्)
यात्रायां यदि विज्ञातमनाक्रन्दमनन्तरम् | व्यासक्तं च प्रमत्तं च दुर्बलं च विचक्षण:
bhīṣma uvāca | yātrāyāṃ yadi vijñātam anākrandam anantaram | vyāsaktaṃ ca pramattaṃ ca durbalaṃ ca vicakṣaṇaḥ ||
毗湿摩说道：“将欲兴师出征，明察之王当即刻探明敌情。若见敌方无盟无援，牵缠于他处战事，疏忽怠惰而势弱；而己军强盛，则善战而勇、具足成事之资的君主，宜下令大军进发。然而当先固守王都与后方，使内境无虞，然后方可击敌。”

Educational Q&A
A righteous and prudent ruler should not rush into war: first gather reliable intelligence, attack only when the enemy is strategically vulnerable, and ensure one’s own homeland and capital are secured before launching an offensive.
In the Shanti Parva’s instruction on kingship and governance, Bhishma teaches Yudhishthira principles of campaign-planning—evaluating the enemy’s weakness and one’s own strength, and prioritizing internal security before marching against an opponent.
