Mahabharata — Anushasana Parva, Shloka 49
स्वाध्याये भोजने चैव दक्षिणं पाणिमुद्धरेत् | यच्छेद्वाड्मनसी नित्यमिन्द्रियाणि तथैव च,स्वाध्याय और भोजनके समय दाहिना हाथ उठाना चाहिये तथा मन, वाणी और इन्द्रियोंको सदा अपने अधीन रखना चहिये
svādhyāye bhojane caiva dakṣiṇaṃ pāṇim uddharet | yacched vāk-manasī nityam indriyāṇi tathaiva ca ||
毗湿摩说道：“行自习诵读吠陀（svādhyāya）之时，与进食之时，当以右手依礼举用。并且应恒常约束言语与心念，同样摄持诸根诸欲。”

Educational Q&A
Maintain disciplined conduct: observe respectful propriety during sacred study and meals, and practice continual restraint over speech, mind, and the senses—key foundations of dharmic life.
In the Anuśāsana Parva’s instruction section, Bhīṣma continues giving Yudhiṣṭhira practical rules of right conduct (sadācāra), focusing here on everyday disciplines that support inner self-mastery.
