Matsya Purana — Uma’s Austerities and the Slaying of the Deceiver Asura ĀḌi
आजगामामररिपुः पुरं त्रिपुरघातिनः स तत्रागत्य ददृशे वीरकं द्वार्यवस्थितम् //
ājagāmāmararipuḥ puraṃ tripuraghātinaḥ sa tatrāgatya dadṛśe vīrakaṃ dvāryavasthitam //
The foe of the gods came to the city of the slayer of Tripura; arriving there, he saw Vīraka stationed at the gate.
Nothing directly—this verse is a narrative moment describing an Asura approaching a city and finding a guardian at the gate, not a Pralaya (cosmic dissolution) teaching.
Indirectly, it highlights the dharma of protection: a properly guarded gate and a vigilant guardian (like Vīraka) reflect the king’s duty to secure cities and maintain order against hostile forces.
Architecturally, the verse foregrounds the city gate (dvāra) as a defended threshold—supporting the broader Purāṇic emphasis on fortifications, gateways, and appointed guardians as key features of protected settlements.
