Mantri-Parīkṣā — Testing Ministers, Securing Counsel, and Ethical Criteria for Advisers (अध्याय ८४)
अनुजुस्त्वनुरक्तो5पि सम्पन्नश्वेतरैर्गुणै: । राज्ञ: प्रज्ञानयुक्तोडपि न मन्त्र श्रोतुमहति,जो अनुरक्त हो, अन्यान्य गुणोंसे सम्पन्न हो और बुद्धिमान् हो, वह भी यदि सरल स्वभावका न हो तो राजाकी गुप्त सलाहको सुननेका अधिकारी नहीं है
anujuṣṭv anurakto 'pi sampannaś cānyair guṇaiḥ | rājñaḥ prajñāna-yukto 'pi na mantraṃ śrotum arhati ||
अनुजुस्त्वनुरक्तोऽपि सम्पन्नश्चेतरैर्गुणैः। राज्ञः प्रज्ञानयुक्तोऽपि न मन्त्रं श्रोतुमर्हति॥
भीष्म उवाच
Loyalty, virtues, and intelligence are insufficient qualifications for hearing a king’s secret counsel; without straightforwardness and inner simplicity, a person is unfit for confidential deliberations because secrecy requires integrity, not merely capability.
In Shanti Parva, Bhishma instructs on rajadharma (the duties and policies of kings). Here he lays down a criterion for who may be admitted to the king’s private consultations, warning that even trusted and capable associates must be excluded if their nature is not guileless.
