Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
ता दृष्ट्वा रहिता गास्तु कचेनाभ्यागता वनात् उवाच वचनं काले देवयान्यथ भार्गवम् //
tā dṛṣṭvā rahitā gāstu kacenābhyāgatā vanāt uvāca vacanaṃ kāle devayānyatha bhārgavam //
Seeing those cows left unattended, Kacha came back from the forest; and at the proper moment Devayānī then spoke these words to the Bhārgava (Kacha).
This verse is purely narrative within the Yayāti–Devayānī–Kacha episode and does not discuss pralaya, cosmology, or dissolution; it sets the scene for Devayānī’s speech to Kacha.
Indirectly, it reflects the dharmic emphasis on proper timing, orderly speech, and attentiveness to protection of valuable dependents (symbolized by unattended cows), themes often extended in Purāṇas to household and royal responsibility.
No Vāstu, temple-building, or ritual procedure is stated in this verse; it functions as a narrative transition into a dialogue.
