Mantri-Parīkṣā — Testing Ministers, Securing Counsel, and Ethical Criteria for Advisers (अध्याय ८४)
नास्य च्छिद्रं पर: पश्येच्छिद्रेषु परमन्वियात् । गूहेत् कूर्म इवाड्रानि रक्षेद् विवरमात्मन:
bhīṣma uvāca |
nāsya chidraṃ paraḥ paśyec chidreṣu param anviyāt |
gūhet kūrma ivāṅgāni rakṣed vivaram ātmanaḥ ||
Bhishma said: “Let no enemy perceive his vulnerabilities; rather, let the king closely investigate the enemy’s weak points. Like a tortoise that draws in its limbs, the king should conceal his inner counsels and carefully guard every opening in his own defenses.”
भीष्म उवाच
A ruler must practice strategic self-guarding: conceal one’s own weaknesses and confidential plans, while diligently identifying the opponent’s vulnerabilities. The tortoise image teaches restraint, containment, and disciplined protection of one’s ‘openings’.
In the Śānti Parva’s instruction on rājadharma, Bhīṣma is advising Yudhiṣṭhira on practical kingship. Here he gives a concise rule of political prudence: do not let enemies detect your weak points; instead, study theirs and keep your counsel protected.
