Mahabharata — Anushasana Parva, Shloka 23
अत्रेः तपोबलप्रकाशः तथा च्यवनस्य सोमाधिकारः
Atri’s Illumination by Tapas; Cyavana and Soma-Entitlement
शूद्रस्य तु कुलं हन्ति वैश्यस्य पशुबान्धवान् । क्षत्रियस्य श्रियं हन्ति ब्राह्मणस्य सुवर्चसम्
śūdrasya tu kulaṃ hanti vaiśyasya paśu-bāndhavān | kṣatriyasya śriyaṃ hanti brāhmaṇasya suvarcasam ||
毗湿摩解释说，不正当的行为——尤其是以违背法（dharma）与清净之道的方式饮食与交往——其道德与社会后果会因人而异：它毁坏首陀罗的家族血脉，毁坏吠舍的牲畜与亲族关系，毁坏刹帝利的富贵昌盛，并损折婆罗门的灵性光辉与美名。
भीष्य उवाच
Educational Q&A
That violations of dharmic discipline—especially regarding food and association—are believed to bring ruin, and the form of ruin is described as differing by social role: lineage for a Śūdra, cattle and kin for a Vaiśya, prosperity for a Kṣatriya, and spiritual radiance/reputation for a Brāhmaṇa.
In the Anuśāsana Parva, Bhīṣma is instructing Yudhiṣṭhira on dharma. Here he states a rule-like consequence statement, warning that improper practices connected with eating/impurity lead to specific kinds of loss for different varṇas.
