Matsya Purana — Solar–Lunar Motions
रोहिण्यार्द्रा मृगशिरो नागवीथिर् इति स्मृता पुष्याश्लेषा पुनर्वस्वोर् वीथी चैरावती स्मृता //
rohiṇyārdrā mṛgaśiro nāgavīthir iti smṛtā puṣyāśleṣā punarvasvor vīthī cairāvatī smṛtā //
Rohiṇī, Ārdrā, and Mṛgaśiras are remembered as belonging to the Nāga‑vīthī (the Serpent star‑path). Likewise, Puṣya, Āśleṣā, and Punarvasu are remembered as belonging to the Cairāvatī‑vīthī.
Nothing directly—this verse is technical jyotiṣa material, classifying nakṣatras into vīthīs (astral groupings), not describing pralaya or cosmological dissolution.
Indirectly, such nakṣatra-groupings support calendrical and electional timing (muhūrta) used by householders and kings for rites, journeys, and state ceremonies; the verse supplies the traditional mapping needed for that astrological reckoning.
Ritually, nakṣatra classifications can guide auspicious timing for saṃskāras and temple rites; architecturally, they may be consulted when choosing consecration (pratiṣṭhā) dates, though this specific verse only lists the vīthī groupings.
