Adhyāya 115: On Restraint Under Verbal Provocation in the Assembly (सभायां आक्रोश-सहिष्णुता)
यदि वाग्भि: प्रयोग: स्यात् प्रयोगे पापकर्मण: । वागेवार्थों भवेत् तस्य न होवार्थों जिघांसत:
yadi vāgbhiḥ prayogaḥ syāt prayoge pāpakarmaṇaḥ | vāg evārtho bhavet tasya na hovārtho jighāṃsataḥ ||
毗湿摩说：若对罪人恶言相向，只以同样的辱骂回击，所得不过是口舌之争。对于一心欲行暴力者，互骂毫无用处，终不能成就任何事。

Do not answer abusive or sinful speech with the same kind of speech; it only multiplies verbal conflict. If someone is bent on violence, insults do not achieve any constructive end—restraint and wise response are implied as the dharmic course.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and right conduct. Here he addresses how to respond to a wrongdoer: mere verbal retaliation is futile, especially when the opponent’s intent is harmful.
