Matsya Purana — The Battle at Tripura: Shiva’s Strategy
स चोडुनाथः ससुतो दिवाकरः स सान्तकस्त्र्यक्षपतिर् महाद्युतिः एते रिपूणां प्रबलाभिरक्षितं तदा बलं संविविशुर्मदोद्धताः //
sa coḍunāthaḥ sasuto divākaraḥ sa sāntakastryakṣapatir mahādyutiḥ ete ripūṇāṃ prabalābhirakṣitaṃ tadā balaṃ saṃviviśurmadoddhatāḥ //
And Coḍunātha, along with his son Divākara, and Sāntaka—the lord of Tryakṣa, of great splendor—these warriors, intoxicated with martial pride, then entered the enemy’s army, strongly guarded by mighty defenders.
Nothing directly—this verse is focused on a martial episode in a royal lineage narrative, describing kings entering a well-guarded enemy army.
It reflects kṣatriya-dharma in the Purāṇic sense: rulers and allied kings are portrayed as leading from the front, confronting protected enemy forces with courage (though the verse also hints at the danger of mada—pride—driving action).
No explicit Vāstu/temple or ritual procedure appears here; the technical focus is military (bala, abhirakṣita) within the Matsya Purana’s dynasty-and-war narration.
