Matsya Purana — Characteristics of Dvāpara and Kali Yugas
द्वात्रिंशे ऽभ्युदिते वर्षे प्रक्रान्तो विंशतिं समाः निजघ्ने सर्वभूतानि मानुषाण्येव सर्वशः //
dvātriṃśe 'bhyudite varṣe prakrānto viṃśatiṃ samāḥ nijaghne sarvabhūtāni mānuṣāṇyeva sarvaśaḥ //
When the thirty-second year had dawned, having set out and spent twenty years (on campaign), he slaughtered all beings—indeed, human beings everywhere, without exception.
Nothing directly about Pralaya is stated here; the verse focuses on a historical/narrative episode of prolonged warfare and indiscriminate killing, not cosmic dissolution.
By highlighting indiscriminate slaughter—especially of humans—it implicitly contrasts with rajadharma, where a king’s use of force is meant to be restrained, lawful, and protective rather than wholesale destruction.
No Vastu, temple-building, iconography, or ritual procedure is mentioned in this verse; it is a narrative statement about the duration and extent of killing during a campaign.
