Matsya Purana — Maya’s Nectar-Reservoir in Tripura and the Revival of the Slain in the Tripur...
तदा शराद्विनिष्पत्य पीतवासा जनार्दनः वृषरूपं महत्कृत्वा रथं जग्राह दुर्धरम् //
tadā śarādviniṣpatya pītavāsā janārdanaḥ vṛṣarūpaṃ mahatkṛtvā rathaṃ jagrāha durdharam //
Then Janārdana, clad in yellow garments, sprang forth swiftly; assuming an immense bull-form, he seized the formidable chariot—hard for any to restrain.
This specific verse is not about pralaya; it highlights Vishnu’s swift, decisive intervention through a powerful manifested form, a recurring puranic theme for restoring order rather than describing cosmic dissolution.
By portraying Janardana acting promptly and fearlessly to control a ‘durdhara’ (hard-to-check) situation, the verse models the dharmic ideal of timely action—kings should restrain disruptive forces and householders should curb harmful impulses with firmness and clarity.
No direct Vāstu or ritual procedure is taught here; the main ritual-iconographic takeaway is the identification of Vishnu as pītavāsā (yellow-robed) and capable of assuming vast, protective forms—useful for pratima-lakṣaṇa (iconographic) interpretation.
