Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
पक्षाभ्यां चारुपत्राभ्याम् आवृत्य दिवि लीलया युगान्ते सेन्द्रचापाभ्यां तोयदाभ्यामिवाम्बरम् //
pakṣābhyāṃ cārupatrābhyām āvṛtya divi līlayā yugānte sendracāpābhyāṃ toyadābhyāmivāmbaram //
At the end of the age, playfully spreading its two wings—lovely as leaves—it covered the sky, like two rain-clouds bearing Indra’s rainbow veiling the heavens.
It depicts a yugānta (end-of-age) atmosphere where the heavens are veiled like by massive rain-clouds—an omen-like cosmic image consistent with pralaya narratives and climatic upheaval.
Indirectly, it supports the Purāṇic ethic of preparedness and humility: rulers and householders should remember the impermanence of worldly order at yugānta and uphold dharma, charity, and restraint rather than pride in power.
No direct Vāstu or ritual rule is stated; the verse mainly provides symbolic cosmography (clouds and rainbow). In ritual reading, such imagery is used to frame pralaya-themed recitations and contemplations on impermanence.
