Shloka 21
अत्रेः तपोबलप्रकाशः तथा च्यवनस्य सोमाधिकारः
Atri’s Illumination by Tapas; Cyavana and Soma-Entitlement
जो ब्राह्मण शूद्रोंके साथ एक पंक्तिमें भोजन कर लेता है, वह अशुद्ध हो जाता है। अतः उनकी शुद्धिके लिये शास्त्रीय विधिके अनुसार यहाँ शौचका विधान है ।।
yastu vaiśyaiḥ sahāśrīyād brāhmaṇo ’py ekabhojane | sa vai trirātraṃ dīkṣitvā mucyate tena karmaṇā ||
ビーシュマは言った。「たとえバラモンであっても、ヴァイシャと同じ列に座して同じ食事を共にすれば、儀礼上の穢れを負う。だが三夜の間、聖別された戒行（ディークシャー）を受けて守るなら、その行為から生じた過失は解かれる。これは、シャーストラが定める行いの境界を守ること、そして贖いの規律によって清浄と社会・宗教の秩序が回復されることを示す。」
भीष्य उवाच
Educational Q&A
The verse teaches that certain forms of commensality are treated as a breach of prescribed ritual-social boundaries, but the tradition also provides a defined expiation: a three-night consecrated observance (trirātra-dīkṣā) to remove the fault and restore purity.
In the Anuśāsana Parva’s instruction on dharma, Bhīṣma lays down a specific rule about eating together (ekabhojana) and states the corresponding prāyaścitta: a brāhmaṇa who has eaten in the same line with vaiśyas should observe a three-night vow to be freed from the resulting impurity.
