Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
यदाश्रित्य घटामो ऽस्य दानवस्य युयुत्सवः ततो हरिरुवाचेदं वज्रायुधमुदारधीः //
yadāśritya ghaṭāmo 'sya dānavasya yuyutsavaḥ tato hariruvācedaṃ vajrāyudhamudāradhīḥ //
“Relying on this plan/support, we shall confront this Dānava, eager for battle.” Then Hari, of noble resolve, spoke these words concerning the thunderbolt-weapon, the Vajra.
This verse does not describe Pralaya; it belongs to a conflict setting where the narrative turns to Hari’s instruction regarding the Vajra-weapon against a Dānava.
Indirectly, it supports the dharmic idea of acting with resolve and proper reliance on wise counsel before engaging in conflict—an ethic applicable to rulers (strategic deliberation) and householders (disciplined, purposeful action).
No Vāstu or temple-architecture rule is stated in this verse; the technical focus is martial—specifically the Vajra as a divine weapon and the transition to Hari’s guidance.
