Matsya Purana — The Tale of Brahmadatta: Past-life Memory
*संनतिरुवाच अकस्मादतिहासस्ते किमर्थमभवन्नृप हास्यहेतुं न जानामि यदकाले कृतं त्वया //
*saṃnatiruvāca akasmādatihāsaste kimarthamabhavannṛpa hāsyahetuṃ na jānāmi yadakāle kṛtaṃ tvayā //
Saṃnati said: “O king, why did this sudden laughter arise in you? I do not know the cause of your mirth—especially since what you did was done at an improper time.”
This verse does not discuss Pralaya; it focuses on human conduct—questioning sudden laughter and an action performed at an improper time.
It highlights the dharmic expectation of self-restraint and propriety: a king’s reactions (like laughter) and actions should be timely and appropriate, since public behavior sets the moral tone of the court and society.
No explicit Vastu or ritual procedure is stated; the key takeaway is the principle of kāla (proper timing), which is also foundational in ritual performance even though architecture is not addressed here.
