Adhyāya 166: Kṛtaghna-doṣa (कृतघ्नदोषः) — the fault of ingratitude and the limits of expiation
काले चतुर्थे भुठ्जानो ब्रह्मचारी व्रती भवेत् । स्थानासनाभ्यां विहरेत त्रिरह्वाभ्युपयन्नप: । एवमेव निराकर्ता यश्षाग्नीनपविध्यति
kāle caturthe bhuñjāno brahmacārī vratī bhavet | sthānāsanābhyāṁ viharet trir ahvābhyupayann apaḥ | evam eva nirākartā yaḥ agnīn apavidhyati |
毗湿摩说道：“当只在规定的第四时进食，住于梵行，严持誓戒。度日当以克制为本——或立或坐——并且每日三次取水以作净化。如此便是为那弃置（怠慢）圣火之人所当行的正当赎罪。”

Educational Q&A
The verse prescribes a disciplined penance: regulated eating, celibacy, vow-observance, restrained posture (standing/sitting), and thrice-daily ritual water-taking, as an expiation for neglecting the sacred household fires.
In Bhishma’s dharma-instruction in the Śānti Parva, he lays down a specific rule of conduct (austerity and purification regimen) to rectify the fault of abandoning or failing to maintain the sacred fires.
