Varṇa-dharma and Rājadharma: Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Outline (वर्णधर्म-राजधर्म-प्रश्नोत्तरम्)
एवमस्त्विति वैन्यस्तु तैरुक्तो ब्रह्म॒वादिभि: । पुरोधाश्चाभवत् तस्य शुक्रो ब्रह्ममयों निधि:
evam astv iti vainyas tu tair ukto brahmavādibhiḥ | purodhāś cābhavat tasya śukro brahmamayo nidhiḥ ||
ବେଦବାଦୀ ମହର୍ଷିମାନେ ‘ଏବମସ୍ତୁ’ ବୋଲି ସମ୍ମତି ଦେଲେ। ତାପରେ ବ୍ରହ୍ମବିଦ୍ୟାର ନିଧି ଶୁକ୍ରାଚାର୍ଯ୍ୟ ତାଙ୍କର ପୁରୋହିତ ହେଲେ।

Legitimate rule is strengthened when the king accepts guidance from Vedic sages and appoints a learned purohita; assent to dharmic counsel (“evam astu”) marks humility and alignment of power with sacred law.
Vainya agrees to the proposal or instruction given by the brahmavādins, and as a consequence Śukra is appointed as his purohita, described as a repository of Vedic wisdom.
