Matsya Purana — Devayānī and Śarmiṣṭhā’s Quarrel
*शौनक उवाच कृतविद्ये कचे प्राप्ते हृष्टरूपा दिवौकसः कचादवेत्य तां विद्यां कृतार्था भरतर्षभ //
*śaunaka uvāca kṛtavidye kace prāpte hṛṣṭarūpā divaukasaḥ kacādavetya tāṃ vidyāṃ kṛtārthā bharatarṣabha //
Śaunaka said: O bull among the Bharatas, when Kaca returned having mastered the sacred vidyā, the dwellers of heaven became radiant with joy; having learned that very vidyā from Kaca, they deemed their purpose fulfilled.
This verse does not address pralaya; it focuses on the successful attainment and transmission of vidyā (sacred knowledge) and the devas’ rejoicing at its recovery.
Indirectly, it upholds the ideal that learning should be completed and applied for rightful ends—suggesting that rulers and householders should value disciplined education and the proper acquisition of knowledge for dharmic goals.
No explicit Vastu or ritual procedure is stated here; the technical emphasis is on vidyā—its mastery and transmission—rather than temple architecture or rites.
