अध्याय १७८ — प्राणवायुगतिः तथा शारीराग्निव्यवस्था
Adhyāya 178 — The courses of prāṇa-vāyu and the regulation of the bodily fire
दम्यनाशकृते मड़किरमृतत्वं किलागमत् । अच्छिनत् काममूलं स तेन प्राप महत्सुखम्
damyanāśakṛte maḍkiramṛtatvaṃ kilāgamat | acchinat kāmamūlaṃ sa tena prāpa mahatsukham ||
ビーシュマは言った。「マドキ（Maḍki）は子牛たちの滅びを契機として不死を得た、と伝えられている。彼は欲（kāma）の根を断ち切った。ゆえに大いなる幸福を得たのである。」

Educational Q&A
Lasting happiness arises from uprooting desire (kāma) rather than merely managing its outward expressions. The verse frames renunciation as a decisive inner act—‘cutting the root’—which leads to great sukha and even ‘amṛtatva’ (deathlessness/spiritual attainment).
Bhīṣma cites the example of the ascetic Maḍki: after an event described as the destruction/loss of calves, Maḍki takes that misfortune as the occasion for deep dispassion, severs desire at its source, and thereby attains immortality and great happiness.
