Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
ददौ स दश धर्माय कश्यपाय त्रयोदश सप्तविंशतिं सोमाय ददौ नक्षत्रसंज्ञिताः देवासुरमनुष्यादि ताभ्यः सर्वमभूज्जगत् //
dadau sa daśa dharmāya kaśyapāya trayodaśa saptaviṃśatiṃ somāya dadau nakṣatrasaṃjñitāḥ devāsuramanuṣyādi tābhyaḥ sarvamabhūjjagat //
He gave ten (daughters) to Dharma, thirteen to Kaśyapa, and twenty-seven—known as the Nakṣatras—to Soma. From those unions arose the entire world, consisting of gods, demons (Asuras), humans, and the rest.
This verse describes creation through lineage (prajā-sarga): by distributing daughters to Dharma, Kaśyapa, and Soma (as Nakṣatras), the world of devas, asuras, humans, and other beings is said to arise—an origin theme rather than a pralaya (dissolution) episode.
It presents the Purāṇic ideal of social-cosmic order maintained through lawful unions and lineage: a householder upholds dharma through sanctioned marriage and progeny, while a king protects that dharmic order that sustains society and the continuity of the world.
No direct Vāstu or temple-building rule is stated; the ritual takeaway is calendrical—Nakṣatras linked to Soma underpin timing for rites (muhūrta), fasts, and ceremonies in later ritual practice.
