Udyoga Parva, Adhyāya 72 — Bhīmasena’s counsel on conciliation and Duryodhana’s disposition
न चैवं नैछिकं कर्म क्षत्रियस्य विशाम्पते । आहुराश्रमिण: सर्वे न भेक्षे क्षत्रिय श्षरेत्,परंतु महाराज! यह क्षत्रियका नैष्ठिक (स्वाभाविक) कर्म नहीं है। सभी आश्रमोंके श्रेष्ठ पुरुषोंका यह कथन है कि क्षत्रियको भीख नहीं माँगनी चाहिये
na caivaṃ naiṣṭhikaṃ karma kṣatriyasya viśāmpate | āhur āśramiṇaḥ sarve na bhikṣe kṣatriyaḥ śrayet ||
And this is certainly not the steadfast, proper vocation of a kṣatriya, O lord of the people. All disciplined men of the āśramas declare that a kṣatriya should not resort to begging.
युधिछिर उवाच
A kṣatriya’s settled duty is to protect and uphold order through rightful means; therefore, begging is presented as incompatible with kṣatriya-dharma and royal dignity, as affirmed by authorities across the āśramas.
Yudhiṣṭhira speaks in a context of deliberation about proper conduct and livelihood, asserting that resorting to begging is not appropriate for a kṣatriya, and citing the consensus of āśrama-following authorities.
