Matsya Purana — Yadu Lineage
बृहस्पतिस्तु संरुद्धं काव्यं ज्ञात्वा वरेण तु तुष्ट्यर्थं दश वर्षाणि जयन्त्या हितकाम्यया //
bṛhaspatistu saṃruddhaṃ kāvyaṃ jñātvā vareṇa tu tuṣṭyarthaṃ daśa varṣāṇi jayantyā hitakāmyayā //
But Bṛhaspati, learning that Kāvya (Śukra) had been restrained by the power of a boon, kept him thus for ten years—through Jayantī—seeking his welfare and intending to secure the satisfaction of the gods.
This verse does not address Pralaya; it focuses on a Deva–Asura episode where Śukra is restrained for a fixed period through the power of a boon and divine strategy.
Indirectly, it highlights a dharmic principle valued in the Purāṇas: acting with hitakāmyā (benevolent intent) and using lawful means (a boon and time-bound restraint) to prevent harm and secure communal welfare.
No Vāstu, temple-building, or ritual procedure is specified in this verse; its technical focus is on boons (vara) and time-bound restraint in a mythic-political context.
