Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
द्विपदश्चाभवन् केचित् केचिद् बहुपदा नराः वलीमुखाः शङ्कुकर्णाः कर्णप्रावरणास् तथा //
dvipadaścābhavan kecit kecid bahupadā narāḥ valīmukhāḥ śaṅkukarṇāḥ karṇaprāvaraṇās tathā //
Some were born two-footed, while some humans came forth with many feet; some had wrinkled or folded faces, some had conch-like ears, and others had ears that served as coverings.
It reflects the post-creation (sarga) theme: creation manifests diverse and even wondrous bodily forms, indicating the vast variability of beings that arise in the cosmic process.
Indirectly, it frames society as comprising many kinds of people; a king’s dharma includes protecting and governing all subjects impartially, regardless of outward form, while householders are guided toward compassion and non-cruelty toward beings.
No direct Vastu or ritual rule appears in this verse; it is primarily cosmological/anthropological, describing varieties of embodied beings rather than temple-building or rites.
