Matsya Purana — Maya’s War-Counsel to the Danavas and the Moonlit Revels in Tripura
काले तस्मिन्पुरे यस्तु संभावयति संहतिम् स एनं कारयेच्चूर्णं बलिनैकैषुणा सुरः //
kāle tasminpure yastu saṃbhāvayati saṃhatim sa enaṃ kārayeccūrṇaṃ balinaikaiṣuṇā suraḥ //
At that time in the city, whoever perceives the enemy’s compact formation (saṃhati) should have a mighty hero reduce it to powder with a single arrow.
This verse is not about cosmic pralaya; it concerns practical protection of a city—recognizing a hostile massed force and neutralizing it swiftly.
It reflects the king’s duty of rakṣaṇa (protection): vigilance in identifying threats and decisive action to safeguard the town and its people.
Within Vastuvidya’s broader city-protection context, it implies defensive preparedness for a fortified settlement—integrating surveillance and rapid response as part of town security practice.
