Udyoga-parva Adhyāya 123 — Bhīṣma–Droṇa–Vidura Upadeśa to Duryodhana
Keśava-vākya aftermath
अस्तु शेषं कौरवाणां मा पराभूदिदं कुलम् | कुलघ्न इति नोच्येथा नष्टकीर्ति्नराधिप,“नरेश्वर! कौरववंश बचा रहे, इस कुलका पराभव न हो और तुम भी अपनी कीर्तिका नाश करके कुलघाती न कहलाओ
astu śeṣaṃ kauravāṇāṃ mā parābhūd idaṃ kulam | kulaghna iti nocyethā naṣṭakīrtir narādhipa ||
হে নরেশ্বর! কৌরবদের যা অবশিষ্ট আছে তা টিকে থাকুক; এই কুল যেন পরাভূত হয়ে ধ্বংসের পথে না যায়। তুমি কীর্তি নষ্ট করে ‘কুলঘাতক’ নামে পরিচিত হয়ো না।
वैशम्पायन उवाच
The verse urges restraint and responsibility: a ruler should protect the continuity of the family/lineage and avoid actions that would brand him a destroyer of his own clan, since such conduct violates ethical duty and ruins lasting reputation.
In Vaiśaṃpāyana’s narration, an admonition is voiced to a kingly figure: preserve what remains of the Kaurava line and do not bring about the clan’s downfall, lest you be remembered with dishonor as a ‘kulaghna’ (clan-slayer).
