Mahabharata — Anushasana Parva, Shloka 22
धर्मनिन्दा–धर्मोपासनाफलम् तथा साध्वाचारलक्षणम्
Fruits of Disparaging vs. Observing Dharma; Marks of Good Conduct
ब्राह्मणत्वं शुभ॑ प्राप्य दुर्लभ॑ यो&वमन्यते । अभोज्यान्नानि चाश्राति स द्विजत्वात् पतेत वै
brāhmaṇatvaṁ śubha prāpya durlabhaṁ yo ’vamanyate | abhojyānnāni cāśnāti sa dvijatvāt pateta vai ||
“吉祥者啊！凡得难得而清净之婆罗门真位，却反以轻慢待之，又食不应食之物者，必定从‘二生’（dvija）之位堕落。”此教诫强调：灵性尊位非仅凭出身而保全，乃在于敬奉自身之法（dharma）与持戒自律之清净行，尤以饮食与克制为要。

Educational Q&A
Brahminhood is rare and must be honored through disciplined conduct; contempt for one’s sacred status and the eating of forbidden/impure food leads to a fall from dvija standing.
Maheśvara instructs an addressed listener (‘śubha’) on dharma: he warns that neglecting the dignity and obligations of Brahminhood—especially by violating food-purity rules—causes spiritual and social degradation from the twice-born status.
