Matsya Purana — Genealogy and Classification of Sacred Fires
सहरक्षः सुराणां तु त्रयाणां ते त्रयो ऽग्नयः एतेषां पुत्रपौत्राश्च चत्वारिंशत्तथैव च //
saharakṣaḥ surāṇāṃ tu trayāṇāṃ te trayo 'gnayaḥ eteṣāṃ putrapautrāśca catvāriṃśattathaiva ca //
Along with Saharākṣa, for those three classes of gods there are three sacred Fires (Agni-deities). And of these, their sons and grandsons are likewise forty in number.
This verse is not describing Pralaya; it is cataloguing divine groupings and the proliferation of Agni-related lineages (Fires and their descendants) within the ongoing cosmic order.
By foregrounding the Agnis (sacred Fires), it indirectly supports the householder’s Vedic duty of maintaining ritual fire and honoring fire-centered rites, which Purāṇas treat as stabilizing dharma in society.
The ritual significance is primary: it points to the theology of multiple Agnis and their lineages, reinforcing the centrality of fire in yajña and domestic rites—background knowledge often presupposed in temple and ritual procedure discussions.
