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 ||
毗湿摩曰：“守此法则，寿命不减：食毕之后，若未洗手漱口，人仍处不净之中。于此不净之时，不可触及三种光明而可敬者——火、牛与婆罗门。以此自律，精气与长寿得以保全。”

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.
