Matsya Purana — The Glory of Prayaga: Pilgrimage
*मार्कण्डेय उवाच कथयिष्यामि ते वत्स यच्छ्रेष्ठं तत्र यत्फलम् पुरा हि सर्वविप्राणां कथ्यमानं मया श्रुतम् //
*mārkaṇḍeya uvāca kathayiṣyāmi te vatsa yacchreṣṭhaṃ tatra yatphalam purā hi sarvaviprāṇāṃ kathyamānaṃ mayā śrutam //
Mārkaṇḍeya said: “Dear child, I shall tell you what is the best among them and what fruit arises from it. For long ago I heard it being expounded for the benefit of all brāhmaṇas.”
This verse does not address pralaya directly; it functions as a transition where Mārkaṇḍeya introduces a teaching on the “best” practice and its resulting merit (phala).
It frames dharma as something to be learned through authoritative transmission (śruti/teachings) and points toward guidance on the most excellent rite—typically relevant to householders and rulers who support brāhmaṇas and uphold religious observances.
No vastu or iconographic rule is stated in this verse; the ritual significance is introductory—announcing an upcoming explanation of a supreme rite/observance and its phala.
