Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
तदा हि प्रेषितो देवैः समीपे वृषपर्वणः तथेत्युक्त्वा तु स प्रायाद् बृहस्पतिसुतः कचः //
tadā hi preṣito devaiḥ samīpe vṛṣaparvaṇaḥ tathetyuktvā tu sa prāyād bṛhaspatisutaḥ kacaḥ //
Then, dispatched by the gods to the presence of Vṛṣaparvan, Kaca—the son of Bṛhaspati—set out, saying, “So be it.”
This verse does not discuss Pralaya; it narrates a Deva–Asura episode where the gods send Kaca to Vṛṣaparvan’s vicinity as part of a strategic mission.
Indirectly, it highlights obedience to rightful command and purposeful action: Kaca accepts the gods’ commission and proceeds—an ethical model of disciplined duty (niyoga) and resolve.
No Vāstu or ritual procedure is stated in this verse; it is a narrative transition marking Kaca’s departure on assignment.
