Matsya Purana — The Episode of Madhu and Kaiṭabha: Gunas
*मधुकैटभावूचतुः नावयोः परमं लोके किंचिदस्ति महामते आवाभ्यां छाद्यते विश्वं तमसा रजसाथ वै //
*madhukaiṭabhāvūcatuḥ nāvayoḥ paramaṃ loke kiṃcidasti mahāmate āvābhyāṃ chādyate viśvaṃ tamasā rajasātha vai //
Madhu and Kaiṭabha said: “O great-minded one, there is nothing whatsoever in the worlds that is superior to us. By us the entire universe is covered—by darkness (tamas) and indeed by passion and turbulence (rajas).”
It portrays a cosmic “veiling” of the universe by tamas and rajas—symbolizing obscuration, chaos, and turbulence that dominate during disorder and dissolution-like conditions.
By highlighting tamas (inertia/ignorance) and rajas (restless passion) as forces that can cover the world, it implicitly supports the Matsya Purana’s ethic that rulers and householders should cultivate sattva—clarity, restraint, and right governance—to prevent social and moral darkness.
No direct Vastu or ritual rule is stated; the takeaway is conceptual: auspicious rites and sacred architecture aim to reduce tamas and regulate rajas through purity, order, and consecration.
