Matsya Purana — The Greatness and Procedure of the Aṅgāra
ब्रह्मन्किमर्थमेतत्ते हास्यमाकस्मिकं कृतम् साधुसाध्विति मामेवम् उक्तवांस्त्वं वदस्व मे //
brahmankimarthametatte hāsyamākasmikaṃ kṛtam sādhusādhviti māmevam uktavāṃstvaṃ vadasva me //
O Brahman, for what reason did you suddenly laugh like this? You said to me, “Well done, well done”—tell me why you spoke so.
This verse itself does not describe pralaya; it functions as a narrative prompt where Manu seeks the reason behind an unexpected laugh and praise, likely introducing an explanation in the following verses.
It models a key dharmic habit: a ruler (Manu) asks respectfully for clarification rather than acting on assumptions, showing deliberation and humility in decision-making.
No explicit Vāstu, temple-building, or ritual procedure is stated in this verse; it is a conversational hinge that may precede technical instruction elsewhere in the chapter.
