Matsya Purana — Description of Atri’s Hermitage: Sacred Grove Planning
सदंष्ट्रारामसरभान् क्रौञ्चाकारकशम्बरान् करालान्कृतमालांश्च कालपुच्छांश्च तोरणान् //
sadaṃṣṭrārāmasarabhān krauñcākārakaśambarān karālānkṛtamālāṃśca kālapucchāṃśca toraṇān //
(One should fashion) archways and ornamental elements as: fierce fanged figures, pleasing śarabha motifs, deer shaped like the krauñca-bird, grim gaping faces, garland-work designs, and also archways bearing “black-tail” features (dark-tufted/black-ended).
Nothing directly—this verse is technical Vastu/ornamentation guidance, listing specific decorative forms for architectural elements like toraṇas (gateways).
It supports dharmic patronage: a king (or wealthy householder) is encouraged to commission properly designed sacred/public structures, where correct ornamental forms are part of maintaining ritual and cultural order.
It specifies acceptable motif-types for architectural decoration—especially toraṇas—indicating that temple/gateway ornamentation should follow recognized iconographic categories (animal forms, fierce faces, garland patterns).
