Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
ततः सिंहसहस्राणि निश्चेरुर्मन्त्रतेजसा कृष्णदंष्ट्राट्टहासानि क्रकचाभनखानि च //
tataḥ siṃhasahasrāṇi niścerurmantratejasā kṛṣṇadaṃṣṭrāṭṭahāsāni krakacābhanakhāni ca //
Then, by the blazing power of the mantra, thousands of lions burst forth—black-fanged, roaring with fierce laughter, and bearing claws that shone like saw-blades.
This verse is not directly about cosmic Pralaya; it highlights a smaller-scale ‘manifestation by mantra-power,’ where protective/terrifying forms are produced through mantra-tejas.
It underscores that protection of society (rakṣā) is supported by disciplined sacred practice—kings and householders are advised in the Purāṇic ethos to uphold dharma through sanctioned rites, guardianship, and restraint rather than mere force.
Ritually, it emphasizes mantra-tejas—the efficacious ‘heat/splendor’ generated by correct recitation and rite—often invoked for protection and warding; no direct Vāstu or temple-measurement rule is stated in this specific verse.
