महिषस्य तु गोमायुः केतोर्हैमस्तदाभवत् ध्वाङ्क्षो ध्वजे तु शुम्भस्य कृष्णायोमयमुच्छ्रितम् //
mahiṣasya tu gomāyuḥ ketorhaimastadābhavat dhvāṅkṣo dhvaje tu śumbhasya kṛṣṇāyomayamucchritam //
For Mahisha, the emblem was the jackal; and Ketu’s standard was then made of gold. On Śumbha’s banner, however, a crow was raised aloft, fashioned of black iron.
This verse does not address Pralaya; it focuses on dhvaja-lakṣaṇa—how specific beings or figures are represented through banner emblems and materials.
In royal and public rituals, correct standards and insignia are part of auspicious statecraft: a king’s ceremonies, processions, and temple patronage require proper iconographic symbols, believed to influence public auspiciousness and omen-reading.
Ritually, it specifies banner emblems and materials (gold, black iron) used for standards—details relevant to temple/ritual paraphernalia and iconographic compliance when installing flags or insignia in ceremonies.
