Jñāna-yoga and Karma-phala: Manu–Bṛhaspati on Akṣara and the Limits of Mantra
सायं प्रातर्मनुष्याणामशन वेदनिर्मितम् । नान्तरा भोजन दृष्टमुपवासी तथा भवेत्
sāyaṃ prātar manuṣyāṇām aśanaṃ vedanirmitam | nāntarā bhojanaṃ dṛṣṭam upavāsī tathā bhavet ||
ビーシュマは言った。「人の食はヴェーダによって二時のみと定められている—朝と夕である。その間に食することを許す規定は見当たらない。この節制を守る者はウパヴァーシン（斎戒する者）と見なされ、断食に等しい功徳を得る。」

Educational Q&A
The verse teaches restraint in food: eating only at the two prescribed times (morning and evening) is a dharmic discipline, and avoiding meals in between is treated as equivalent in merit to fasting.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and right conduct; here he lays down a rule of regulated eating grounded in Vedic authority, linking daily discipline with the spiritual fruit of upavāsa.
