Ācāra-vidhi (Rules of Conduct) — Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Catalogue
श्रितो मूर्धानमात्मा तु शरीरं परिपालयन् । प्राणो मूर्थनि चाग्नौ च वर्तमानो विचेष्टते,आत्मा मस्तकके रन्ध्रस्थानमें स्थित होकर सम्पूर्ण शरीरकी रक्षा करता है और प्राण मस्तक तथा अग्नि दोनोंमें स्थित होकर शरीरको चेष्टाशील बनाता है
śrito mūrdhānam ātmā tu śarīraṃ paripālayan | prāṇo mūrdhani cāgnau ca vartamāno viceṣṭate ||
