कुम्भेन रत्नचित्रेण केतुर् अश्विनयोर् अभूत् हेममातंगरचितं चित्ररत्नपरिष्कृतम् //

For the Aśvinī, the twin horsemen, the emblem (ketu) was a jewel-adorned pot (kumbha), fashioned with golden-elephant workmanship and refined with variegated gems.
This verse does not discuss Pralaya; it focuses on iconographic/ritual detailing—specifically the prescribed emblem (ketu) associated with the Aśvins.
It supports dharmic duty indirectly: kings and householders who sponsor rites or temples are instructed to follow correct traditional specifications for sacred emblems and ornamentation to ensure ritual propriety and auspiciousness.
It specifies an auspicious emblem: a jewel-adorned kumbha as the Aśvins’ identifying mark, emphasizing prescribed materials (gold-work, gem inlay) used in temple/ritual objects and decorative standards.
