Matsya Purana — The Gods Seek Śiva’s Refuge: The Cosmic Chariot Prepared for the Burning of T...
तस्मिंश्च वीर्यवृद्ध्यर्थं वासुकिर्नागपार्थिवः तेजःसंवसनार्थं वै मुमोचातिविषो विषम् //
tasmiṃśca vīryavṛddhyarthaṃ vāsukirnāgapārthivaḥ tejaḥsaṃvasanārthaṃ vai mumocātiviṣo viṣam //
In that undertaking, Vāsuki—the sovereign of the Nāgas—released a most virulent poison, intending thereby to increase potency and to serve as a fiery, radiant covering for the work at hand.
This verse is not describing Pralaya directly; it depicts a mythic mechanism of unleashed cosmic hazard (deadly poison) used within a divine undertaking, a theme that often parallels how immense forces must be contained and regulated in Purāṇic cosmology.
By portraying Vāsuki as a “nāga-pārthiva” (a ruler) who unleashes a powerful but dangerous force for a defined purpose, the verse indirectly reflects the ethical ideal that power must be deployed intentionally and responsibly—never aimlessly—an important principle for kingship and disciplined household life.
No direct Vāstu or temple-building rule is stated; however, the imagery of “tejaḥ-saṃvasana” (a radiant covering/enveloping blaze) aligns with ritual symbolism of protective enclosures and controlled energies (e.g., safeguarding sacred work through prescribed containment and purification).
