Chapter 49: Sañjaya’s Enumeration of the Pāṇḍava Coalition (पाण्डवसैन्यसमागम-वर्णनम्)
यस्य वीर्येण सहसा चत्वारो भुवि पाण्डवा:
yasya vīryeṇa sahasā catvāro bhuvi pāṇḍavāḥ
サञ्जयは言った。「その武威によって、突如として力がみなぎり、地上のパーンダヴァ四兄弟は断乎として行動し得たのである。」
संजय उवाच
The line foregrounds the ethical weight of vīrya (heroic power): decisive action in the world often depends on the strength and character of a central figure, implying that power should be aligned with dharma rather than mere impulse.
Sañjaya is describing events and attributing the Pāṇḍavas’ effective, forceful capability to the prowess of a particular person (implied by “whose”), setting up praise or explanation of that figure’s decisive influence.
