Matsya Purana — The Battle at Tripura: Shiva’s Strategy
तेन नादेन त्रिपुराद् दानवा युद्धलालसाः उत्पत्य दुद्रुवुश्चेलुः सायुधाः खे गणेश्वरान् //
tena nādena tripurād dānavā yuddhalālasāḥ utpatya dudruvuśceluḥ sāyudhāḥ khe gaṇeśvarān //
Stirred by that thunderous roar, the Dānavas—eager for battle—leapt up from Tripura and rushed forth; armed, they surged through the sky toward the hosts of the Gaṇa-lords.
This verse does not describe pralaya; it depicts martial mobilization in the Tripura cycle—Dānavas reacting to a mighty sound and moving into open conflict.
Indirectly, it functions as a dharmic warning: uncontrolled ‘yuddha-lālasā’ (lust for battle) is portrayed as an asuric impulse, contrasting with the Purāṇic ideal that rulers wage war only as a last resort for protection and order.
The key term is ‘Tripura’ (the triple city/fortress), which in the larger Tripura narrative becomes a symbol of formidable constructed power; this verse itself emphasizes the city’s martial occupants rather than explicit Vāstu or ritual procedure.
