Rājadharma
बाह्ुमा भ्यन्तरं चैव पौरजानपदं तथा । चारै: सुविदितं कृत्वा ततः कर्म प्रयोजयेत्,गुप्तचरोंद्वारा नगर तथा छोटे ग्रामोंक बाहटी और भीतरी समाचारोंको अच्छी तरह जानकर फिर उसके अनुसार कार्य करे
bāhyam ābhyantaraṃ caiva paurajānapadaṃ tathā | cāraiḥ suviditaṃ kṛtvā tataḥ karma prayojayet ||
ビーシュマは言った。「王は密偵を用いて、外と内の情勢、さらに都の民と郷里の民のありさまを徹底して確かめよ。しかる後、その知見に従って政（まつりごと）と施策を動かし始めるべきである。」

Educational Q&A
A ruler should not act on impulse or hearsay; after carefully verifying both external and internal conditions—especially the sentiments of urban and rural subjects—through reliable intelligence, he should implement actions that fit the realities on the ground.
In the Shanti Parva’s instruction on rājadharma, Bhishma advises the king on practical governance: first gather accurate information via spies about the realm’s internal/external situation and the people’s condition, and only then proceed with administrative or political action.
