Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
ऊरोर् अजनयत् पुत्रान् षड् आग्नेयी तु सुप्रभान् अग्निं सुमनसं ख्यातिं क्रतुमङ्गिरसं गयम् //
ūror ajanayat putrān ṣaḍ āgneyī tu suprabhān agniṃ sumanasaṃ khyātiṃ kratumaṅgirasaṃ gayam //
From Ūru, the Agneyī (fire-born) lady Suprabhā gave birth to six illustrious sons—Agni, Sumanas, Khyāti, Kratu, Aṅgiras, and Gaya.
This verse is not about Pralaya; it belongs to the creation-era genealogical narration, listing the progeny born in the early cosmic generations.
Indirectly, it supports the Purāṇic model of dharma through lineage: social and ritual duties are traditionally framed through ancestry (vaṁśa), ṛṣi-lines, and progenitors who establish sacrificial and ethical norms.
The key ritual signal is the name Kratu (sacrifice/rite) and the Agneyī association (fire principle), pointing to the centrality of sacred fire (agni) in Vedic-Purāṇic ritual systems, though no specific Vāstu or temple rule is stated in this verse.
