Matsya Purana — Prayaga Mahatmya Begins: Yudhishthira’s Remorse
*मार्कण्डेय उवाच शृणु राजन्महाबाहो क्षत्रधर्मव्यवस्थितम् नैव दृष्टं रणे पापं युध्यमानस्य धीमतः //
*mārkaṇḍeya uvāca śṛṇu rājanmahābāho kṣatradharmavyavasthitam naiva dṛṣṭaṃ raṇe pāpaṃ yudhyamānasya dhīmataḥ //
Mārkaṇḍeya said: “Listen, O king of mighty arms, to the established code of Kṣatriya duty. For the wise man who fights in battle, no sin is seen (incurred) in war.”
This verse does not address Pralaya; it focuses on Rajadharma—specifically that duty-bound battle, when aligned with Kshatriya law, is not counted as sin for the wise warrior.
It instructs the king in Kshatriya duty: warfare undertaken as a righteous obligation (not from greed or cruelty) is treated as dharmic and not sinful for a prudent ruler fulfilling his protective role.
No Vastu, temple-building, or ritual procedure is mentioned in this verse; its significance is ethical—defining the moral status of combat when performed according to Kshatriya-dharma.
