Matsya Purana — Characteristics of Dvāpara and Kali Yugas
एवं संध्यांशके काले सम्प्राप्ते तु युगान्तिके तेषामधर्मिणां शास्ता भृगूणां च कुले स्थितः //
evaṃ saṃdhyāṃśake kāle samprāpte tu yugāntike teṣāmadharmiṇāṃ śāstā bhṛgūṇāṃ ca kule sthitaḥ //
Thus, when the twilight-fraction of the age arrived—at the very verge of the yuga’s end—there appeared a chastiser of those unrighteous ones, established in the lineage of the Bhṛgus.
It points to the yuga’s terminal “twilight” (saṃdhyā-aṃśa), a liminal end-time when adharma peaks and a corrective force arises; it implies moral and cosmic transition rather than describing physical pralaya directly.
By emphasizing a “śāstā” who restrains the unrighteous, it mirrors the king’s dharmic role as disciplinarian—protecting social order, punishing adharma, and restoring lawful conduct during periods of decline.
No explicit Vāstu or ritual procedure is stated; the verse is primarily ethical-esoteric, framing yugānta as a time that necessitates strict regulation and restoration of dharma rather than temple-building rules.
