Matsya Purana — The Battle at Tripura: Shiva’s Strategy
रुद्रदत्तं तदा दीप्तं दीप्तानलसमप्रभम् वज्रं वज्रनिभाङ्गस्य दानवस्य ससर्ज ह //
rudradattaṃ tadā dīptaṃ dīptānalasamaprabham vajraṃ vajranibhāṅgasya dānavasya sasarja ha //
Then he hurled the blazing vajra—bestowed by Rudra—shining with the splendor of a flaming fire, against that Dānava whose limbs were like adamant.
This verse is not about Pralaya; it depicts a martial episode where a Rudra-bestowed vajra is hurled against a Dānava, emphasizing divine intervention through consecrated weaponry.
Indirectly, it models the dharmic principle that power should be wielded as a sanctioned instrument against disruptive forces (adharma), not as personal wrath—mirroring the king’s duty to protect order using legitimate means.
No Vāstu or temple-architecture rule is stated; the ritual undertone is the idea of a weapon empowered by a deity (Rudra-datta), reflecting the Puranic theme of consecration and divine authorization.
