आचारप्रशंसा
Praise of Ācāra as the Basis of Longevity, Fame, and Prosperity
आगननिं गां ब्राह्मणं चैव तथा हायुर्न रिष्यते । भीगे पैर भोजन करनेवाला मनुष्य सौ वर्षोतक जीवन धारण करता है। भोजन करके हाथ-मुँह धोये बिना मनुष्य उच्छिष्ट (अपवित्र) रहता है। ऐसी अवस्थामें उसे अग्नि
agnim gāṁ brāhmaṇaṁ caiva tathā āyur na riṣyate | bhuktvā pāṇi-mukhaṁ aśaucam apohya na spraśet trīn tejasvinaḥ ||
ビーシュマは言った。「この規則を守っても寿命は損なわれぬ。食後、手と口を洗わぬかぎり、人はなお不浄である。その不浄の身で、光明にして尊ぶべき三つ――火、牛、婆羅門――に触れてはならぬ。かく自らを律すれば、精気と長寿は保たれる。」

Educational Q&A
After eating, one should wash hands and mouth; until then one is considered impure (ucchiṣṭa/aśauca) and should not touch the sacred triad—fire, cow, and Brahmin. This discipline is presented as protective of one’s vitality and longevity.
In the Anushasana Parva’s instruction on dharma and proper conduct, Bhishma advises Yudhishthira on everyday rules of cleanliness and reverence, linking personal purity with respect toward sacred beings and with the preservation of life-force.
