Matsya Purana — Yayāti in Amarāvatī-like Splendor: Devayānī Installed
देवयान्या तु सहितः स नृपो नहुषात्मजः विजहार बहूनब्दान् देववन्मुदितो भृशम् //
devayānyā tu sahitaḥ sa nṛpo nahuṣātmajaḥ vijahāra bahūnabdān devavanmudito bhṛśam //
Accompanied by Devayānī, that king—the son of Nahusha—sportively enjoyed himself for many years, exceedingly delighted, like one of the gods.
Nothing directly—this verse is genealogical-narrative, describing a king’s long enjoyment with Devayānī, not cosmic creation or pralaya.
It portrays royal life emphasizing pleasure and prosperity; in Purāṇic ethics this typically functions as narrative setup—enjoyment is shown as possible for a king, but later episodes often balance it with dharma, responsibility, and the consequences of indulgence.
None explicitly—no Vāstu, temple-building, or ritual procedure is stated in this verse; it is focused on dynastic storytelling.
