Adhyāya 166: Kṛtaghna-doṣa (कृतघ्नदोषः) — the fault of ingratitude and the limits of expiation
अन्न वीर्य ग्रहीतव्यं प्रेतकर्मण्यपातिते । त्रिषु त्वेतेषु पूर्वेषु न कुर्वीत विचारणाम्
anna vīrya grahītavyaṃ pretakarmaṇy apātite | triṣu tv eteṣu pūrveṣu na kurvīta vicāraṇām |
ビーシュマは言った。「葬送の儀礼(プレータ・カルマン)がまだ行われていなくとも、家の者はなお、死者の穀物と財を引き取るべきである。先に挙げた三種の大罪人—酒に溺れる者、バラモン殺し、師の妻を犯す者—については、この件に関しさらに思案をめぐらすべきではない。」
भीष्म उवाच
For certain grave sinners previously listed (drunkard, Brahmin-slayer, and violator of the guru’s wife), normal post-death considerations are curtailed: even if funerary rites are not performed, the household may take over the deceased’s provisions and wealth, and one should not hesitate or reopen the question.
In the Shanti Parva’s dharma instruction, Bhishma is laying down a rule about how a family should act when a person of extreme sin dies—specifically regarding whether to perform obsequial rites and how to handle the deceased’s property and sustenance.
