Matsya Purana — The Rite of the Jaggery-Cow
धेनुवत्सौ घृतास्यौ च सितसूक्ष्माम्बरावृतौ शुक्तिकर्णाविक्षुपादौ शुचिमुक्ताफलेक्षणौ //
dhenuvatsau ghṛtāsyau ca sitasūkṣmāmbarāvṛtau śuktikarṇāvikṣupādau śucimuktāphalekṣaṇau //
Both are to be like a cow with her calf; their mouths are as though anointed with ghee; they are covered in fine white garments; their ears are like mother-of-pearl shells; their feet like sugarcane; and their eyes resemble pure pearls, or fruits with a pearly lustre.
This verse does not discuss pralaya; it focuses on auspicious visual characteristics (lakṣaṇas) used for describing or assessing sacred figures/images.
Indirectly, it supports dharma by guiding patrons (kings/householders) in commissioning or venerating properly characterized sacred forms—ensuring worship is aligned with śāstric norms.
These are pratima-lakṣaṇa style descriptors—used in ritual/temple contexts to define auspicious features for sacred representations and to avoid inauspicious or non-śāstric forms in installation and worship.
