Matsya Purana — Vishnu’s Battle with Mathana
तस्मिन्पराङ्मुखे दैत्ये महिषे शुम्भदानवः संदष्टौष्ठपुटः कोपाद् भ्रुकुटीकुटिलाननः //
tasminparāṅmukhe daitye mahiṣe śumbhadānavaḥ saṃdaṣṭauṣṭhapuṭaḥ kopād bhrukuṭīkuṭilānanaḥ //
When that buffalo-demon turned away, the asura Śumbha, biting his lips in wrath, his face twisted by a furrowed brow, seethed with anger.
This verse does not discuss Pralaya; it focuses on a battle moment, portraying Śumbha’s anger as the buffalo-demon turns away.
Indirectly, it serves as a cautionary portrait of krodha (anger): the tightening of lips and knitted brow signal loss of inner restraint—contrary to the self-control praised for rulers and householders in dharma teachings.
No Vāstu/temple-architecture or ritual procedure is mentioned; the verse is purely narrative, emphasizing emotion and battlefield posture.
