Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
शूद्रां धात्रेयिकां तस्माव् अन्धाय प्राहिणोत्तदा तस्यां कक्षीवदादींश्च शूद्रयोनाव् ऋषिर् वशी //
śūdrāṃ dhātreyikāṃ tasmāv andhāya prāhiṇottadā tasyāṃ kakṣīvadādīṃśca śūdrayonāv ṛṣir vaśī //
Oleh itu, pada waktu itu raja menghantar seorang wanita Śūdra bernama Dhātreyikā kepada Andha; dan melalui wanita itu, resi yang menguasai diri memperanakkan Kakṣīvān dan yang lain-lain, lahir dari rahim Śūdra.
Nothing directly—this verse is genealogical, describing lineage and birth through a particular womb rather than cosmic dissolution or the Great Flood narrative.
Indirectly, it reflects Purāṇic social-history themes: alliances, progeny, and lineage transmission. In royal/householder ethics, such passages are used to frame ancestry, legitimacy, and the continuity of family lines rather than prescribing a specific duty here.
None is stated in this śloka; it is not a Vāstu/temple-building or ritual-procedure verse but a brief note in a genealogy/ṛṣi-lineage context.
