Matsya Purana — Maya’s Nectar-Reservoir in Tripura and the Revival of the Slain in the Tripur...
त्रिपुरे तु महान्घोरो भेरीशङ्खरवो बभौ दानवा निःसृता दृष्ट्वा देवदेवरथे सुरम् //
tripure tu mahānghoro bherīśaṅkharavo babhau dānavā niḥsṛtā dṛṣṭvā devadevarathe suram //
But in Tripura there arose a mighty and terrifying roar of war—kettle-drums and conch-shell blasts. Seeing the god upon the chariot of the Lord of gods, the Dānavas rushed out to confront him.
This verse does not describe cosmic creation or Pralaya; it depicts the outbreak of war in Tripura, marked by conch and drum signals, as the Dānavas mobilize on seeing the deity’s chariot.
Indirectly, it reflects the dharmic theme of preparedness and decisive response to imminent threat: the battlefield signals (conch/drum) represent organized mobilization—an ideal also valued in rajadharma (statecraft and defense), though the verse itself is mythic.
Ritually, the bherī (war-drum) and śaṅkha (conch) indicate auspicious yet martial sound-rites used to announce major actions; architecturally, “Tripura” evokes the fortified triple-city motif, but no specific Vastu/temple rule is stated in this verse.
