Matsya Purana — Solar–Lunar Motions
पूर्वोत्तरप्रोष्ठपदौ गोवीथी रेवती स्मृता श्रवणं च धनिष्ठा च वारुणं च जरद्गवम् //
pūrvottaraproṣṭhapadau govīthī revatī smṛtā śravaṇaṃ ca dhaniṣṭhā ca vāruṇaṃ ca jaradgavam //
The pair called Pūrvaproṣṭhapadā and Uttaraproṣṭhapadā is known as Govīthī; Revatī is remembered so; likewise Śravaṇa and Dhaniṣṭhā, and also Vāruṇa and Jaradgava.
Nothing directly—this verse is a technical catalog of nakṣatra names/epithets used for calendrical and astronomical identification, not a Pralaya narrative.
By fixing correct nakṣatra nomenclature, it supports choosing auspicious timings (muhūrta) for royal acts, rites, travel, donations, and household saṃskāras—an applied Jyotiṣa utility rather than an ethical injunction.
Indirectly ritual: accurate nakṣatra identification is used to time consecrations, vows, and temple/house ceremonies; the verse itself lists names rather than giving Vāstu rules.
