Mahabharata Santi Parva Chapter 360:2

Mahabharata Santi Parva (Mokshadharma Parva) Chapter 360:2 The Naga said, 'I had no arrogance due to pride. In consequence, however, of my birth, the measure of my arrogance was considerable. Of wrath, which is born of desire, O blessed lady, I have none. It has all been consumed by the fire of thy excellent instructions. I do not behold, O blessed dame, any darkness that is thicker than wrath. In consequence, however, of the Naga having excess of wrath, they have become object of reproach with all persons.[] By succumbing to the influence of wrath, the ten-headed Ravana of great prowess, became the rival of Sakra and was for that reason slain by Rama in battle. Hearing that the Rishi Rama of Bhrigu's race had entered the inner apartments of their palace for bringing away the calf of the Homa cow of their sire, the sons of Kartavirya, yielding to wrath, took such entry as an insult to their royal house, and as the consequence thereof, they met with destruction at the hands of Rama. Indeed, Kartavirya of great strength, resembling the Thousand-eyed Indra himself, in consequence of his having yielded to wrath, was slain in battle by Rama of Jamadagni's race. Verily, O amiable lady at thy words I have restrained my wrath, that foe of penances that destroyer of all that is beneficial for myself. I praise my own self greatly since, O large-eyed one, I am fortunate enough to own thee for my wife,—thee that are possessed of every virtue and that hast inexhaustible merits. I shall now proceed to that spot where the Brahmana is staying. I shall certainly address that Brahmana in proper words and he shall certainly go hence, his wishes being accomplished.'
