उद्योगपर्व — अध्याय १४० (कृष्णेन कर्णं प्रति पाण्डवबल-वैशिष्ट्यप्रदर्शनम्) / Udyoga Parva, Chapter 140
Krishna’s appraisal of Pandava advantage and war portents
मन्त्रस्थ नियम॑ कुर्यस्त्विमत्र मधुसूदन । एतदत्र हित॑ मन्ये सर्व यादवनन्दन
mantrastha niyamaṁ kuryās tv iha atra madhusūdana | etad atra hitaṁ manye sarva yādavanandana ||
カルナは言った。「マドゥスーダナよ、この密談については秘匿の掟を守り、ここまでにとどめてほしい。ヤドゥ族の歓びよ、私はこれこそがここでの全き益だと考える――あなたと私の間で私的に語られたことは、決して漏らされてはならぬ。」
कर्ण उवाच
The verse underscores the ethical discipline of confidentiality in counsel: private deliberations (mantra) should be protected, because discretion can prevent harm, preserve trust, and support prudent decision-making in a volatile political context.
Karna addresses Kṛṣṇa after a private exchange, urging him to keep their discussion secret and not to carry it further. Karna frames this restraint as the most beneficial course in the present situation, where disclosure could alter alliances and intensify conflict.
