Adhyāya 90: Babhruvāhana’s Reception and the Commencement of Yudhiṣṭhira’s Aśvamedha
प्राणधारणमात्रेण शकक्यं कर्तु तपस्त्वया । प्राणो हि परमो धर्म: स्थितो देहेषु देहिनाम्,प्राणधारणमात्रसे आप तप कर सकते हैं। देहधारियोंके शरीरोंमें स्थित हुआ प्राण ही परम धर्म है
prāṇadhāraṇamātreṇa śakyaṃ kartuṃ tapas tvayā | prāṇo hi paramo dharmaḥ sthito deheṣu dehinām ||
儿子说道：“只要维系你的生命之息，你便能修行苦行。因为正是那住于一切有身众生之身中的生命气息（prāṇa），乃至高的法（dharma）。”
