Adhyāya 166: Kṛtaghna-doṣa (कृतघ्नदोषः) — the fault of ingratitude and the limits of expiation
उदक्यामासते ये च द्विजा: केचिदनग्नय: । होम॑ चाश्रोत्रियं येषां ते सर्वे पापकर्मिण:
udakyāmāsate ye ca dvijāḥ kecid anagnayaḥ | homaṃ cāśrotriyaṃ yeṣāṃ te sarve pāpakarmiṇaḥ ||
ビーシュマは言った。「月経中の女と交わる婆羅門、家の聖火を保たぬ者、そしてヴェーダに拠らぬ(許されぬ)作法で供犠を行う者——そのすべては罪業をなす者と見なされるべきである。」この教えは、婆羅門の倫理的威徳が、節度ある行いと定められた儀礼への忠実さと切り離せないことを示す。

The verse teaches that ethical and ritual discipline are essential to dharma: sexual restraint regarding prohibited times, maintaining the sacred fire as a marker of household religious duty, and performing rites in accordance with Vedic authorization are presented as standards; violating them is labeled pāpa (sinful conduct).
In the Shanti Parva’s instruction on dharma, Bhishma enumerates categories of Brahmins whose conduct is censured, using them as examples to define boundaries of proper behavior and correct ritual practice.
