Daṇḍanīti and the King as the Cause of Yuga-Order (दण्डनीतिः राजधर्मश्च युगकारणत्वम्)
परिखाश्लैव कौरव्य प्रतोलीर्निष्कुटानि च । न जात्वन्य: प्रपश्येत गुह्ममेतद् युधिष्ठिर
parikhāś caiva kauravya pratolīr niṣkuṭāni ca | na jātvan anyaḥ prapaśyet guhyam etad yudhiṣṭhira ||
毗湿摩说道：“俱卢后裔啊，这些护城壕、门楼与内围之所，当布置得使外人永不得见。此事机密，由提施提罗啊。”

Educational Q&A
A ruler must protect the kingdom through prudent, discreet planning—especially regarding defenses and strategic infrastructure. Security measures should not be exposed to outsiders, because secrecy can prevent exploitation and thereby safeguard subjects.
In the Śānti Parva’s instruction on kingship, Bhīṣma teaches Yudhiṣṭhira practical principles of governance. Here he emphasizes that fortifications and inner defensive arrangements (moats, gates, enclosures) are to be kept confidential so that enemies or rivals cannot assess vulnerabilities.
