युद्धे अङ्गद-मैन्द-द्विविद-राक्षसयुद्धम्; कुम्भस्य प्रादुर्भावः तथा सुग्रीवेण पराभवः (Sarga 76: Angada and the Vanara chiefs battle Kampana, Prajaṅgha, Yūpākṣa, Śoṇitākṣa; Kumbha enters and is checked by Sugrīva)
ततःकुम्भस्समुत्पत्यसुग्रीवमभिपद्य च ।आजघानोरसिक्रुद्धोवज्रवेगेनमुष्टिना ।।।।
tataḥ kumbhaḥ samutpatya sugrīvam abhipadya ca |
ājaghānorasi kruddho vajravegena muṣṭinā ||
Then Kumbha sprang back up, rushed at Sugriva, and in anger struck him on the chest with a fist that fell like a thunderbolt.
Then Kumbha hit Sugriva in anger with his fist at the speed of a thunderbolt on his chest.
It illustrates how anger (krodha) drives violence in war; dharma requires that force be governed by purpose and restraint, not by uncontrolled fury.
After being thrown into the sea, Kumbha recovers and retaliates by landing a powerful blow to Sugrīva’s chest.
For Kumbha: ferocity and aggressive resolve; implicitly, the epic contrasts this with the higher virtue of self-mastery.
