Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
रतिर्मनस्तपो बुद्धिर् महान् दिक्सम्भ्रमस् तथा ततः स शतरूपायां सप्तापत्यान्यजीजनत् //
ratirmanastapo buddhir mahān diksambhramas tathā tataḥ sa śatarūpāyāṃ saptāpatyānyajījanat //
Rati, Manas, Tapa, Buddhi, Mahān, and also Diksambhrama—thus, from her, upon Śatarūpā, he begot seven offspring.
It reflects creation (sarga) by listing personified principles/qualities as offspring in Manu’s line, emphasizing emanation and ordering of reality rather than dissolution (pralaya).
Indirectly, it grounds dharma in lineage and cosmic order: the householder’s role of progeny and continuity mirrors the Purāṇic idea that social stability and righteous rule rest on properly maintained generations.
No direct Vāstu or ritual procedure is stated; the verse is primarily genealogical/cosmological, though terms like Buddhi and Mahān later inform philosophical frameworks sometimes used in ritual and iconographic interpretation.
