उद्योगपर्व — विदुरनीतिः (Adhyāya 37): आयुःक्षयहेतवः, नीतिसूत्राणि, बलभेदाः, पाण्डव-विग्रहदोषदर्शनम्
धर्मे चार्थे च कामे च स राजा राजसत्तम: । गूढमन्त्रस्य नृपतेस्तस्य सिद्धिरसंशयम्
dharme cārthe ca kāme ca sa rājā rājasattamaḥ | gūḍhamantrasya nṛpates tasya siddhir asaṃśayam ||
जो राजा—राजसत्तम—धर्म, अर्थ आणि काम या तिन्ही बाबतीत आपला मंत्र गुप्त ठेवतो, त्या नृपाला निःसंशय सिद्धी प्राप्त होते.
विदुर उवाच
A ruler’s success in the three aims of life—dharma, artha, and kāma—depends greatly on disciplined secrecy in counsel and strategy; indiscreet speech and leaked plans undermine both ethics and effective governance.
In the Udyoga Parva, Vidura offers political and ethical counsel in a tense pre-war setting; here he emphasizes that a king who guards confidential deliberations is assured of successful outcomes in policy, prosperity, and orderly enjoyment.
