Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
सोमांशस्य च तस्यापि दक्षस्याशीतिकोटयः वक्ष्ये तासां तु विस्तारं लोके यः सुप्रतिष्ठितः //
somāṃśasya ca tasyāpi dakṣasyāśītikoṭayaḥ vakṣye tāsāṃ tu vistāraṃ loke yaḥ supratiṣṭhitaḥ //
And of that very Dakṣa—who is also a portion of Soma—there are eighty koṭis (vast multitudes) of progeny. I shall describe in detail their expansion, which is firmly established and renowned in the world.
It focuses on creation-era expansion: the immense progeny attributed to Dakṣa (linked here with Soma) and the intent to detail their proliferation, rather than describing dissolution (pralaya).
Indirectly, it supports Purāṇic social memory: kings and householders trace lineage, legitimacy, and ritual obligations (śrāddha, gotra remembrance) through such genealogies, which the text frames as ‘well established in the world’.
No Vāstu or temple-rule detail appears in this verse; its ritual relevance is genealogical—providing lineage context often used for rites connected to ancestors and progenitors like Dakṣa.
