Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
महाशनीं वज्रमयीं मुमोचाशु शतक्रतुः तयाशन्या पतितया दैत्यस्याचलरूपिणः //
mahāśanīṃ vajramayīṃ mumocāśu śatakratuḥ tayāśanyā patitayā daityasyācalarūpiṇaḥ //
Śatakratu (Indra) swiftly hurled the great thunderbolt, made of vajra. Struck down by that falling bolt, the Daitya—whose form was like an immovable mountain—collapsed.
This verse does not address pralaya or cosmic dissolution; it depicts a martial episode where Indra’s vajra overpowers a Daitya, emphasizing divine force rather than cosmology.
Indirectly, it models the Purāṇic ideal of decisive action against adharmic forces—an image often used to support the king’s duty to protect order and remove threats to society.
No explicit Vāstu or ritual procedure is stated; the key technical term is vajramayī aśanī (adamantine thunderbolt), a mythic weapon motif rather than a temple/ritual prescription.
