आचारप्रशंसा
Praise of Ācāra as the Basis of Longevity, Fame, and Prosperity
जो मनुष्य पूर्व दिशाकी ओर मुँह करके भोजन करता है, उसे दीर्घायु, जो दक्षिणकी ओर मुँह करके भोजन करता है उसे यश, जो पश्चिमकी ओर मुख करके भोजन करता है उसे धन और जो उत्तराभिमुख होकर भोजन करता है उसे सत्यकी प्राप्ति होती है ।।
bhīṣma uvāca | yaḥ purvadig-abhimukhaḥ kṛtvā bhuṅkte sa dīrghāyur bhavati; yaḥ dakṣiṇābhimukhaḥ kṛtvā bhuṅkte sa yaśasvī bhavati; yaḥ paścimābhimukhaḥ kṛtvā bhuṅkte sa dhanaṃ prāpnoti; yaś cottarābhimukhaḥ kṛtvā bhuṅkte sa satyaṃ prāpnoti || agnim ālabhya toyena sarvān prāṇān upaspṛśet | gātrāṇi caiva sarvāṇi nābhiṃ pāṇitale tathā ||
毗湿摩说道：向东而食者得长寿；向南而食者得名声；向西而食者得财富；向北而食者得真实。既触圣火之后，当以水依仪触净诸气（诸命息）与全身诸肢，亦及脐与双掌，以守饮食与清净之法度。

Educational Q&A
Bhishma links everyday conduct to ethical and auspicious outcomes: the direction one faces while eating is presented as shaping life-goals (longevity, fame, wealth, truth), and he emphasizes ritual purity—touching fire and then water to purify the body and vital functions—before or around the act of eating.
In the Anushasana Parva’s instruction on dharma and proper conduct, Bhishma continues advising on household discipline and purity practices, giving prescriptive rules about mealtime orientation and a brief procedure of ritual touching (fire, then water) as part of regulated daily life.
