राज्ञा राजैव योद्धव्यस्तथा धर्मो विधीयते । नान्यो राजानमभ्यस्थेदराजन्य: कथउ्चन,राजाको राजाके साथ ही युद्ध करना चाहिये। उसके लिये यही धर्म विहित है। जो राजा या राजकुमार नहीं है, उसे किसी प्रकार भी राजापर अस्त्र-शस्त्रोंका प्रहार नहीं करना चाहिये
rājñā rājaiva yoddhavyas tathā dharmo vidhīyate | nānyo rājānam abhyasthed arājanyaḥ kathaṃcana ||
Bhīṣma said: “A king should be fought only by a king; such is the rule of dharma that is laid down. No one who is not of the royal warrior order—no non-king and no non-prince—should, under any circumstance, assail a king with weapons.”
भीष्म उवाच
Bhīṣma states a rule of righteous warfare: combat against a king is properly undertaken only by another king (i.e., by rightful royal-kṣatriya peers). Those outside that status should not strike a king with weapons, emphasizing restraint, hierarchy, and regulated violence.
In Śānti Parva’s instruction on dharma and governance, Bhīṣma lays down norms for royal conduct and warfare. Here he specifies who is entitled to engage a king in battle, framing it as a prescribed dharmic rule.
