Matsya Purana — Manifestation of Kauśikī
स तु सिंहः करालास्यो जटाजटिलकंधरः प्रोद्धूतलम्बलाङ्गूलो दंष्ट्रोत्कटमुखातटः //
sa tu siṃhaḥ karālāsyo jaṭājaṭilakaṃdharaḥ proddhūtalambalāṅgūlo daṃṣṭrotkaṭamukhātaṭaḥ //
That lion should be portrayed with a gaping, fearsome mouth; with a neck thickly matted with tawny mane; with a long tail flung upward in a vigorous sweep; and with cheeks and jaws made formidable by protruding fangs.
This verse does not describe Pralaya; it gives iconographic specifications—how a lion (often a protective emblem in temple contexts) should be depicted with fearsome features.
Indirectly, it supports dharmic duties through patronage: kings and householders commissioning temples and images should follow śāstric standards so sacred spaces remain ritually correct and socially protective.
It is a pratima-lakṣaṇa guideline: the lion’s open mouth, prominent fangs, mane-like neck, and raised tail are prescribed markers for a proper fierce/protective temple motif used in gateways, pillars, and guardian ensembles.
