[4]Moreover, looking at your own duty, you should not waver; for there is nothing higher for a Kshatriya than a righteous war.

स्वधर्ममपि चावेक्ष्य न विकम्पितुमर्हसि। धर्म्याद्धि युद्धाच्छ्रेयोऽन्यत्क्षत्रियस्य न विद्यते॥
svadharmam api cāvekṣya na vikampitum arhasi / dharmyāddhi yuddhāc chreyo 'nyat kṣatriyasya na vidyate
"For a warrior, there is nothing higher than a righteous battle — this is your svadharma."
