Udyoga-parva 35
विदुर उवाच तपो दमो ब्रह्मवित्तं विताना: पुण्या विवाहा: सततान्नदानम् | येष्वेवैते सप्त गुणा वसन्ति सम्यग्वृत्तास्तानि महाकुलानि
vidura uvāca—tapo damo brahmavittaṃ vitānāḥ puṇyā vivāhāḥ satatānna-dānam | yeṣv evaite sapta guṇā vasanti samyag-vṛttās tāni mahā-kulāni ||
维杜罗说道：大王啊，凡是确有这七种德行安住其中的家族——苦行修持（tapas）、自制（dama）、通达吠陀与梵（Brahman）之智、维持祭祀（yajña）之礼、清净合法的婚姻、恒常施食、以及端正的行止——才应当被称为“伟大而高贵”的宗族。

Educational Q&A
Nobility of birth is validated by lived virtues: discipline, self-restraint, Vedic/Brahman-knowledge, sustaining sacred rites, pure marriage practices, continual food-charity, and upright conduct. A ‘great family’ is defined ethically, not merely by ancestry.
In Vidura’s counsel to the king during the Udyoga Parva’s tense pre-war deliberations, he sets a moral standard for what counts as true high lineage, redirecting attention from pride of birth to dharmic behavior and public-minded virtue.
