Matsya Purana — Maya’s War-Counsel to the Danavas and the Moonlit Revels in Tripura
कुरुध्वं निर्भयाः काले कोकिलाशंसितेन च स कालः पुष्ययोगस्य पुरस्य च मया कृतः //
kurudhvaṃ nirbhayāḥ kāle kokilāśaṃsitena ca sa kālaḥ puṣyayogasya purasya ca mayā kṛtaḥ //
Act without fear at the proper time—indicated by the auspicious call of the kokilā (cuckoo); for that time has been ordained by me for the Puṣya-yoga and for the founding of a city.
This verse is not about Pralaya; it focuses on constructive sacred timing—choosing an auspicious muhurta (Puṣya-yoga) and favorable omens for establishing a city.
It supports the duty of rulers and householders to begin major works (like founding a settlement) only at sanctioned auspicious times, aligning governance and prosperity with dharmic omens and calendrical discipline.
It specifies muhurta selection for purasthāpana: Puṣya-yoga is recommended, and natural omens (the cuckoo’s call) are treated as ritual confirmation for proceeding with city-planning activity.
