Matsya Purana — The Slaying of Tāraka: Skanda’s Śakti and the Victory of the Devas
गतासुः स पपातोर्व्यां प्रलये भूधरो यथा विकीर्णमुकुटोष्णीषो विस्रस्ताखिलभूषणः //
gatāsuḥ sa papātorvyāṃ pralaye bhūdharo yathā vikīrṇamukuṭoṣṇīṣo visrastākhilabhūṣaṇaḥ //
Bereft of life, he fell upon the earth—like a mountain collapsing at the time of cosmic dissolution (pralaya)—his crown and diadem scattered, and all his ornaments loosened and cast down.
It uses pralaya as the supreme metaphor for collapse: even the mightiest fall suddenly and completely, like a mountain giving way during cosmic dissolution.
By showing royal insignia (crown, ornaments) scattered at death, it underscores that status is temporary; a king or householder should prioritize dharma and right conduct over pride in power or display.
No direct Vāstu or ritual instruction appears; the verse is primarily a poetic simile (mountain in pralaya) used to convey the totality of downfall and impermanence.
