Matsya Purana — Hiranyakashipu’s Boons
दैत्यदानवसंघास्ते सर्वे ज्वलितकुण्डलाः स्रग्विणो वाग्मिनः सर्वे सदैव चरितव्रताः //
daityadānavasaṃghāste sarve jvalitakuṇḍalāḥ sragviṇo vāgminaḥ sarve sadaiva caritavratāḥ //
Those hosts of Daityas and Danavas—all of them—wore blazing earrings; all were garlanded, eloquent in speech, and ever steadfast in the vows and disciplines they had undertaken.
This verse does not address pralaya directly; it focuses on a descriptive portrayal of Daitya–Danava hosts, emphasizing their ornaments, eloquence, and disciplined observances.
Indirectly, it highlights ideals of disciplined conduct (vrata) and controlled speech (vāgmin), traits praised across dharma literature; even adversarial beings are depicted as possessing order, vows, and rhetorical skill—qualities a king or householder should cultivate ethically.
No explicit Vastu or ritual procedure is stated, but the details—kundalas (earrings) and garlands—serve as iconographic markers useful for identifying Daitya/Danava figures in Puranic-themed temple sculpture and visual programs.
