Matsya Purana — Tripura’s Prosperity
चतस्रः प्रमदास्तत्र त्रयो मर्त्या भयावहाः कोपानलादीप्तमुखाः प्रविष्टास् त्रिपुरार्दिनः //
catasraḥ pramadāstatra trayo martyā bhayāvahāḥ kopānalādīptamukhāḥ praviṣṭās tripurārdinaḥ //
There, four celestial maidens and three dreadful mortals appeared—terrifying in aspect—entering before Tripurārdin (Śiva, the destroyer of the three cities) with faces blazing like the fire of wrath.
This verse does not describe cosmic Pralaya directly; it depicts a fierce, localized theophany—wrathful, fear-inducing manifestations accompanying Tripurārdin (Śiva) in the Tripura episode.
Indirectly, it reinforces a Purāṇic ethical theme: uncontrolled wrath (kopa) is a destructive force, while divine wrath is portrayed as purposeful—aimed at removing adharma. Kings are repeatedly urged in Purāṇas to restrain personal anger and wield punishment only as dharma requires.
The verse itself is not a Vāstu/temple-rule injunction; however, by naming Tripurārdin it alludes to the Tripura myth, often used in ritual storytelling and Śiva worship contexts (e.g., commemorative recitations), rather than giving concrete Matsya Purāṇa Vāstu Śāstra tips.
