Matsya Purana — Uma’s Austerities and the Slaying of the Deceiver Asura ĀḌi
कृत्वा मुखान्तरे दन्तान् दैत्यो वज्रोपमान्दृढान् तीक्ष्णाग्रान् बुद्धिमोहेन गिरिशं हन्तुमुद्यतः //
kṛtvā mukhāntare dantān daityo vajropamāndṛḍhān tīkṣṇāgrān buddhimohena giriśaṃ hantumudyataḥ //
Having fashioned within his mouth teeth—hard as thunderbolts (vajra) and sharp-pointed—the Daitya, his understanding deluded, set out with the intent to slay Girīśa (Śiva).
This verse does not describe pralaya; it highlights moral-cosmic disorder (moha) where a demon, deluded in intellect, attempts violence against Śiva—an example of adharma provoking divine reassertion of order.
It warns against बुद्धिमोह (delusion of judgment): rulers and householders must govern desires and anger, since reckless intent to harm—even when empowered—leads to ruin and social disorder in Purāṇic ethics.
No Vāstu or ritual procedure is stated here; the key takeaway is symbolic—‘vajra-hard, sharp teeth’ portrays weaponized aggression born from delusion, rather than any temple-building or rite.
