Prāyaścitta and Contextual Non-Culpability (प्रायश्चित्त-निमित्त-अदोषवाद)
महाव्रतं चरेद् यस्तु दद्यात् सर्वस्वमेव तु । गुर्वर्थे वा हतो युद्धे स मुच्येत् कर्मणो5शुभात्,स्त्रियाँ भी एक वर्षतक मिताहार एवं संयमपूर्वक रहनेपर उक्त पापकर्मोसे मुक्त हो जाती हैं। जो महाव्रतका (एक महीनेतक जल न पीनेके नियमका) पालन करता है, ब्राह्मणोंको अपना सर्वस्व समर्पित कर देता है अथवा गुरुके लिये युद्धमें मारा जाता है, वह अशुभ कर्मके बन्धनसे मुक्त हो जाता है
mahāvrataṃ cared yas tu dadyāt sarvasvam eva tu | gurvarthe vā hato yuddhe sa mucyeta karmaṇo'śubhāt ||
Vyāsa said: Whoever undertakes the great vow, or gives away his entire wealth, or is slain in battle for the sake of his teacher—such a person is released from the bondage of inauspicious deeds. The teaching emphasizes that severe self-discipline, complete generosity, and self-sacrifice in loyal service can function as powerful means of moral purification.
व्यास उवाच
The verse teaches that certain intense forms of dharmic commitment—a severe vow (tapas), total giving (dāna), or dying in battle for one’s teacher (guru-sevā)—can cleanse a person of inauspicious karmic bonds, highlighting purification through discipline, generosity, and self-sacrifice.
Vyāsa is explaining modes of expiation and moral purification within the Shānti Parva’s broader instruction on dharma: he lists exemplary acts that are considered powerful enough to free a person from the consequences of wrongful deeds.
