परुषमुक्तो हि तेजस्वी तेजसा प्रत्यारोहति ॥ कZ_०८.३.२५ ॥
paruṣamukto hi tejasvī tejasā pratyārohati
For a spirited person, once addressed harshly, rises in retaliation with (his own) force and ardor.
Harsh speech can provoke immediate retaliation, turning minor disputes into violent incidents; regulating abuse helps prevent escalation and maintain order.
