atha tasya vacaḥ śrutvā bhrātur nidhanasaṃśrayam | pradharṣayitum ārebhe muniṃ krodhān niśācaraḥ || 3.11.66 ||
Then, hearing those words that confirmed his brother’s death, the night-ranger, enraged, began to assault the sage.
On hearing the news of the death of his brother, the demon Ilvala, out of anger, started attacking the sage.
Uncontrolled krodha leads to adharma; instead of accepting the result of wrongdoing, Ilvala chooses further violence against a righteous sage.
After learning Vātāpi is dead, Ilvala reacts with rage and moves to attack Agastya.
By contrast, the virtue upheld by the sage is kṣamā/śama (self-control), while Ilvala embodies its opposite.
