Mahabharat
संवादे परुषाण्य आहुर युधिष्ठिर नराधमाः परत्याहुर मध्यमास तव एतान उक्ताः परुषम उत्तरम ॥ २-६५-७ ॥
'Those who are virtuous remember only the good deeds of their foes, not the hostile acts committed against them. Moreover, the good-hearted perform acts of kindness without expecting anything in return. O Yudhishthira, only those of the lowest character resort to harsh words in disputes.' ॥ 2-65-7 ॥
