Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
जनयामास धर्मात्मा म्लेच्छान्सर्वाननेकशः स सृष्ट्वा मनसा दक्षः स्त्रियः पश्चादजीजनत् //
janayāmāsa dharmātmā mlecchānsarvānanekaśaḥ sa sṛṣṭvā manasā dakṣaḥ striyaḥ paścādajījanat //
That righteous one brought forth all the Mlecchas in many varieties; and Dakṣa—having first created them by his mind (manasā)—afterwards generated women.
This verse concerns sarga (creation), not pralaya: it describes Dakṣa’s mental creation and subsequent generation of women, indicating orderly emanation of beings rather than dissolution.
Indirectly, it grounds social life in progeny and regulated generation: the emergence of women and human groups frames later dharma teachings on marriage, lineage, and governance over diverse peoples.
No Vāstu or temple-architecture rule is stated here; the verse is genealogical/cosmogonic, serving as background to later ritual and societal prescriptions in the Matsya Purana.
