एष त्रयीधर्मश्चतुर्णां वर्णानामाश्रमाणां च स्वधर्मस्थापनादौपकारिकः ॥ कZ_०१.३.०४ ॥
eṣa trayī-dharmaś caturṇāṃ varṇānām āśramāṇāṃ ca sva-dharma-sthāpanād aupakārikaḥ
这一吠陀三部(trayī)之所以有益,是因为它确立各自的本分(svadharma)——四种社会阶序(varṇa)与人生四期(āśrama)的本分。
To justify Vedic-legal learning as a governance asset: by fixing role-based duties across society, the state gains predictability, social discipline, and lower friction in administration and adjudication.
Modern states similarly rely on clear role definitions and enforceable norms (constitutions, administrative law, professional codes). When duties and jurisdictions are well-specified, compliance improves and enforcement costs fall.
No specific official is named here; the implied duty of the ruler is to uphold a stable normative-legal order by recognizing and institutionalizing role-based obligations, thereby supporting public order and welfare.
