Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
भुजंगश्च महापद्मः सर्पः कर्कोटकस्तथा चित्रसेनश्च गन्धर्वः पूर्णायुश्चैव गायनौ //
bhujaṃgaśca mahāpadmaḥ sarpaḥ karkoṭakastathā citrasenaśca gandharvaḥ pūrṇāyuścaiva gāyanau //
Bhujaṅga, Mahāpadma, Sarpa, and likewise Karkoṭaka; and the Gandharva Citrāsena, and also Pūrṇāyu—these are renowned celestial singers.
This verse does not describe Pralaya directly; it functions as a catalog of prominent Nāgas and Gandharva singers, reflecting the Purana’s broader cosmological mapping of beings across realms.
Indirectly, such enumerations support Purāṇic learning (itihāsa–purāṇa-śravaṇa) valued for rulers and householders as part of dharmic education—knowing sacred lineages, classes of beings, and traditional names used in ritual recitation.
No Vāstu or temple-building rule is stated here; the ritual relevance is mainly nominative—these names may appear in Purāṇic recitations and mythic-hymnic contexts involving Nāgas and Gandharvas.
