Matsya Purana — Prayaga Mahatmya Begins: Yudhishthira’s Remorse
ये च तत्र महात्मानः समेताः पाण्डवाः स्मृताः कुन्ती च द्रौपदी चैव ये च तत्र समागताः भूमौ निपतिताः सर्वे रुदन्तस्तु समन्ततः //
ye ca tatra mahātmānaḥ sametāḥ pāṇḍavāḥ smṛtāḥ kuntī ca draupadī caiva ye ca tatra samāgatāḥ bhūmau nipatitāḥ sarve rudantastu samantataḥ //
And there, those great-souled ones—the Pāṇḍavas who had assembled—along with Kuntī and Draupadī and all others who had gathered there, all fell down upon the ground, weeping on every side.
This verse does not describe Pralaya; it depicts a human scene of collective grief, using emotional narration to underline impermanence and the weight of dharmic trials.
By portraying even renowned dharmic figures overwhelmed by sorrow, the verse implicitly teaches restraint, compassion, and steadiness—qualities expected of rulers and householders when facing calamity and loss.
No Vastu/temple-building or ritual procedure is specified here; the focus is narrative (lamentation and prostration), not architectural or liturgical instruction.
