In the battle, the two brothers—stupefied by rage—struck each other with palms and feet like thunder, and with fists like thunderbolts.
The brothers, insensate with fury, struck each other like thunder with their palms, soles and fists in the combat.
Uncontrolled anger (krodha) is shown as a force that eclipses reason and brotherly duty, turning kinship into violence—an implicit warning aligned with dharma’s call for restraint.
Vali and Sugriva exchange heavy blows in close combat, with rage driving the intensity of the fight.
Primarily an anti-virtue is highlighted: loss of self-mastery; the verse illustrates how fury can overpower discernment.
