Matsya Purana — Purūravas Witnesses the Sports of Apsarases and Gandharvas; Attains the Grace...
रात्र्यामस्यां व्यतीतायाम् अत्रिणा त्वं समेष्यसि तेन राजन्समागम्य कृतकृत्यो भविष्यसि //
rātryāmasyāṃ vyatītāyām atriṇā tvaṃ sameṣyasi tena rājansamāgamya kṛtakṛtyo bhaviṣyasi //
When this night has passed, you will meet the sage Atri; and, O King, upon meeting him, you will become one whose purpose is fulfilled.
This verse does not address Pralaya; it focuses on a forthcoming meeting with Sage Atri as the key event that will bring fulfillment of the king’s aim.
It presents a rajadharma motif: a king attains clarity and success by seeking and meeting a qualified rishi (here, Atri), implying that righteous governance is guided by sage-counsel and dharmic instruction.
No Vastu Shastra or temple-ritual procedure is stated in this verse; the significance is relational and ethical—meeting the right sage is portrayed as the decisive step toward accomplishing one’s duty.
