Shloka 18
अत्रेः तपोबलप्रकाशः तथा च्यवनस्य सोमाधिकारः
Atri’s Illumination by Tapas; Cyavana and Soma-Entitlement
मृतकस्य त्रिरात्रे यः समुद्दिष्टे समश्षुते । सप्त त्रिषवर्णं स्नात्वा पूतो भवति ब्राह्मण:
mṛtakasya trirātre yaḥ samuddiṣṭe samaśnute | sapta triṣavarṇaṃ snātvā pūto bhavati brāhmaṇaḥ ||
ビーシュマは言った。「もしバラモンが、死に関わって供された食（すなわち死の不浄にある家の食）を三夜続けて口にするなら、七日間、朝・正午・夕の三つの時刻の節目に沐浴して清められる。これは、死に由来する不浄に触れた後、法（ダルマ）が儀礼的清浄を重んじ、定められた方法でそれを回復させることを示す教えである。」

Educational Q&A
Contact with death-related impurity through eating food offered in that context creates ritual defilement, and dharma prescribes a specific purification: thrice-daily bathing for seven days, emphasizing disciplined restoration of purity rather than denial of the transgression.
In Anuśāsana Parva’s dharma-instruction, Bhīṣma lays down a rule about a brāhmaṇa who repeatedly eats in a household under death-impurity and states the required purificatory practice to regain ritual fitness.
