Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
*मत्स्य उवाच या सा देहार्धसम्भूता गायत्री ब्रह्मवादिनी जननी या मनोर्देवी शतरूपा शतेन्द्रिया //
*matsya uvāca yā sā dehārdhasambhūtā gāyatrī brahmavādinī jananī yā manordevī śatarūpā śatendriyā //
Lord Matsya said: She who was born from half of his body—Gayatrī, the knower and utterer of Brahman—she who became the mother, the divine consort of Manu, is Śatarūpā, ‘of a hundred forms’, endowed with a hundred faculties (senses/powers).
It focuses on creation and lineage: Shatarūpā arises as a primordial mother-figure (linked with Gayatrī and sacred knowledge), establishing the human line through Manu rather than describing dissolution.
By presenting Manu’s divine consort as ‘brahma-vādinī’ (rooted in sacred wisdom), it implies that righteous governance and household life should be grounded in Vedic discipline, learning, and progeny-supporting dharma.
The explicit ritual cue is Gayatrī—central to daily recitation and initiation (sandhyā, japa). While not a Vāstu rule, it anchors ritual orthopraxy that later supports temple and household rites described elsewhere in the Matsya Purana.
